Abstract

A control device for obtaining a uniform or even winding is provided for a winding machine for winding strand-shaped winding material, and includes an electrical scanning device which detects the transition from a winding layer into a next higher winding layer by detecting the step that is formed during such transition. The scanning device does not make physical contact with the winding layer but relies on detection information furnished by opto-electrical or acousto-electrical sensing elements. This information is used to control the reversing of movement of a feed drive which effects the relative reciprocating traversing movement between the spool and a strand guide.

Description

Die Erfindung betrifft eine Wickelmaschine zum Aufwickeln von strangförmigem Wickelgut auf eine Spule, welcher das Wickelgut über einen Strangführer zugeführt wird, mit einem Verlege- antrieb für eine längs einander hin- und hergehende Changierbewegung von Spule und Strangführer, wobei der Verlegeantrieb bei Aufsteigen des Wickelgutes an einem Spulenflansch nach einem vorgegebenen Programm während des Übergangs in die nächst höhere Wickellage gesteuert wird.The invention relates to a winding machine for winding strand-shaped winding material onto a spool, to which the winding material is fed via a strand guide, with a laying drive for a reciprocating longitudinally reciprocating movement of the spool and strand guide, the laying drive starting when the winding material rises a coil flange is controlled according to a specified program during the transition to the next higher winding position.

Wenn bei derartigen Wickelmaschinen während der Ausbildung einer Wickellage die Wickelgut-Auflaufstelle bis an einen Spulenflansch herangelaufen ist, müssen zur Erzielung eines guten Wickelbildes und zum exakten Ausfüllen des verbleibenden Zwickelraumes eine Reihe spezieller Verlegebewegungen ausgeführt werden, damit ein regelmäßiger Übergang in die nächste Wickellage erreicht wird. Üblicherweise wird zwischen den beiden Spulenflanschen das Wickelgut mit einem Rückhaltewinkel zugeführt, um eine enge Anlage der Windungen zu gewährleisten. Die Verlegebewegungen werden bei den bekannten Wickelmaschinen entweder durch ein axiales Verfahren der Spule oder durch ein zur Spulenachse paralleles Verfahren des Strangführers ausgeführt. Ein bei Anlaufen der Wickelgutauflaufstelle an einem Spulenflansch üblicherweise (DE-PS 15 74 425) ausgeführtes Programm von Verlegebewegungen besteht aus

  • 1) Parallelziehen des Wickelgutes zum Flansch für eine bestimmte Spulenumdrehung bis Aufbauen der ersten Windung oder nächsten Wickellage,
  • 2) Wegziehen des Wickelgutes vom Flansch, um ein Aufklettern der Windungen am Flansch in die übernächste Lage zu vermeiden,
  • 3) nach einer bestimmten weiteren Spulendrehung Zurückschwenken des Wickelgutes zur Einstellung des gewünschten Rückhaltewinkels für das Wickeln in der nächsten Wickellage.
If, in the case of such winding machines, the winding material take-up point has run up to a coil flange during the formation of a winding layer, a number of special laying movements must be carried out in order to achieve a good winding pattern and to exactly fill the remaining gusset space so that a regular transition to the next winding position is achieved . Usually, the material to be wound is fed with a retaining angle between the two coil flanges in order to ensure that the windings fit tightly. In the known winding machines, the laying movements are either by an axial movement of the coil or by a movement of the coil parallel to the coil axis Strand leader executed. A program of laying movements which is usually carried out when the winding material take-up point starts at a coil flange (DE-PS 15 74 425) consists of
  • 1) pulling the winding material parallel to the flange for a specific spool revolution until the first turn or next winding layer is built up,
  • 2) pulling the winding material away from the flange in order to prevent the windings on the flange from climbing up into the position after that,
  • 3) after a certain further spool rotation, swiveling the winding material back to set the desired retention angle for winding in the next winding position.

Für eine ordnungsgemäße Verlegung ist von entscheidender Bedeutung, das Anlaufen der Wickelauflaufstelle an einen Flansch oder das Aufsteigen einer neuen Wickellage am.Flansch zuverlässig zu erkennen, damit das danach auszuführende Programm immer zum exakt richtigen Zeitpunkt eingeschaltet wird.For proper installation, it is vitally important to reliably identify the start of the winding overrun point on a flange or the ascent of a new winding layer on the flange so that the program to be executed afterwards is always switched on at exactly the right time.

Durch die DE-PS 15 74 425 und 19 02 722 sind Wickelmaschinen mit Changierantrieb für die Spule bekannt, bei denen am Gestell der Wickelmaschine Endschalter zur Erfassung der von der Spulenlänge abhängigen Endstellungen angeordnet sind, die in Verbindung mit weiteren Endschaltern, die abhängig vom Zulaufwinkel des Wickelgutes gesteuert werden, die Verlegebewegungsabläufe beim Übergang in eine nächste Wickellage steuern. Die dortige Erfassung und Steuerung des Verlegeantriebes beim Übergang in die nächste Wickellage ist aber konstruktiv aufwendig und erfordert exakte mechanische Einstellungen. Durch die US-PS 39 51 355 ist es bekannt, das Aufsteigen einer neuen Wickellage mittels berührungslos arbeitender Näherungsschalter zu erfassen.From DE-PS 15 74 425 and 19 02 722 winding machines with traversing drive for the coil are known, in which limit switches are arranged on the frame of the winding machine for detecting the end positions dependent on the coil length, which in conjunction with further limit switches which depend on the inlet angle of the winding material can be controlled, control the laying movement sequences during the transition to a next winding position. The detection and control of the laying drive there during the transition to the next winding position is structurally complex and requires exact mechanical settings. From US-PS 39 51 355 it is known to detect the rise of a new winding layer by means of a proximity switch that operates without contact.

Diese müssen aber von Wickellage zu Wickellage über gesonderte Schrittschaltmotore angehoben werden, wodurch die dortige Anordnung verhältnismäßig aufwendig und störanfällig wird. Durch die DE-OS 25 56 484 ist ferner eine Kabelwickelmaschine bekannt, bei welcher der Aufstieg in eine neue Wickellage durch Lagenwächter erfaßt wird, die einen mit einem Gleitschuh auf dem Wickel aufliegenden, gegen Federkraft anhebbaren Schwenkarm aufweisen, wobei beim Hochschwenken der Arme ein elektrisches Signal ausgelöst wird. Solche Lagenwächter mit unmittelbar am Wickelgut angreifenden Tast- oder Gleitstücken sind jedoch vielfach ungeeignet, selbst verschleißanfällig und können u.U. empfindlicheres Wickelgut beschädigen.However, these must be raised from winding position to winding position by means of separate stepping motors, which makes the arrangement there relatively complex and prone to failure. From DE-OS 25 56 484 a cable winding machine is also known, in which the ascent into a new winding position is detected by layer guards, who have a swivel arm which rests with a sliding shoe on the winding and can be raised against spring force, with an electrical one when the arms are swung up Signal is triggered. Such position monitors with tactile or sliding pieces directly attacking the material to be wound are often unsuitable, even susceptible to wear and may, under certain circumstances, damage more sensitive material to be wound.

Der Erfindung liegt die Aufgabe zugrunde, Wickelmaschinen..der anstehenden Art mit einer sehr preiswerten und völlig stör- und verschleißfreien Einrichtung zur Erfassung des Aufsteigens der Windungen in eine Wicklungslage auszurüsten.The invention has for its object to equip winding machines .. of the type in question with a very inexpensive and completely trouble-free and wear-free device for detecting the ascent of the turns in a winding position.

Die Lösung dieser Aufgabe ist erfindungsgemäß erreicht durch eine strangführerseitig angeordnete, optoelektrische oder akustoelektrische Abtasteinrichtung zur Überwachung der Wickellagenstufe in der Wickelkontur, welche einen Abtastbereich mindestens gleich der maximalen Bewicklungsdicke der Spule besitzt und welche jeweils bei Auftreten einer neuen Wickellagenstufe eine Einschaltung des Steuerungsprogramms für den Übergang in die nächste Wickellage auslöst.This object is achieved according to the invention by an optoelectric or acoustoelectric scanning device arranged on the strand guide side for monitoring the winding layer stage in the winding contour, which has a scanning area at least equal to the maximum winding thickness of the coil and which each time the control program for the transition is switched on when a new winding layer stage occurs triggers in the next winding position.

Die Erfindung bietet den entscheidenden Vorteil, daß nunmehr die Überwachung des Aufsteigens einer neuen Wickellage von einer fest angeordneten Abtasteinrichtung aus erfolgt, welche berührungslos arbeitet wie die Näherungsschalter nach der US-PS 39 51 355, die aber selbst nicht mehr Lage für Lage verstellt werden muß. Damit entfallen bei der Vorrichtung nach der Erfindung alle verschleißanfälligen, mechanischen Verstelleinrichtungen. Darüber hinaus bedarf die Abtasteinrichtung nach der Erfindung keiner jeweiligen Einstellung auf den Durchmesser des Wickelgutes oder auf die Spulenbreite. Bei dem Typ von Wickelmaschinen, bei dem die Spule die Changierbewegung ausführt, ist die Abtasteinrichtung ortsfest und vorzugsweise am Strangführer angebracht. Führt dagegen der Strangführer die Changierbewegung aus, ist die Abtasteinrichtung nach der Erfindung starr am Strangführer anzuordnen, da sie dann die Changierbewegungen mitausführen muß.The invention offers the decisive advantage that the monitoring of the rise of a new winding position is now carried out from a fixedly arranged scanning device, which works contactlessly like the proximity switch according to US Pat. No. 3,951,355, but which itself no longer has to be adjusted layer by layer . This eliminates all ver in the device according to the invention wear-prone, mechanical adjustment devices. Moreover, the scanning device need not according to the invention each setting to the diameter of the winding material or the S pulenbreite. In the type of winding machine in which the bobbin carries out the traversing movement, the scanning device is stationary and is preferably attached to the strand guide. If, on the other hand, the strand guide executes the traversing movement, the scanning device according to the invention is to be arranged rigidly on the strand leader, since it must then also carry out the traversing movements.

Gemäß einer bevorzugten Ausgestaltung der Erfindung kann vorgesehen werden, daß die Abtasteinrichtung erst durch Verschwinden der während der Ausbildung einer Wickellage beobachteten Wickellagenstufe in Bereitschaft zur Erfassung einer neuen Wickellagenstufe geschaltet wird. Infolge dieser Maßnahme haben Eingriffe in das Beobachtungsfeld der Abtasteinrichtung während des normalen Wickelvorganges keine Auswirkung, so lange die normale Wickellagenstufe noch beobachtet werden kann. Es hat somit auch keinen Einfluß, wenn ein Flansch zum Ende einer Wickellage in das Beobachtungsfeld eintritt. Erst wenn nach Legen der letzten Windung die beobachtete Wickellagenstufe in der letzten Wickellage verschwunden ist, ist die Abtasteinrichtung wieder sensibilisiert, um eine neue Änderung zu erfassen. In dieser Situation ist die nächste zu erwartende Änderung das Aufsteigen der ersten Windung der neuen Wickellage, so daß nur bei Erfassung dieses Vorganges das Umsteuerungsprogramm für den Übergang in die nächste Wickellage ausgelöst wird. Damit ist eine sehr zuverlässig arbeitende, von Störeinflüssen weitgehend freie Umsteuerung des Wickelprozesses beim Übergang in die nächst höhere Wickellage erreicht, was einen wesentlichen Schritt bei dem Ziel der vollständigen Automatisierung solcher Wickelprozesse darstellt.According to a preferred embodiment of the invention, it can be provided that the scanning device is switched to readiness for detection of a new winding layer stage only when the winding layer stage observed during the formation of a winding layer disappears. As a result of this measure, interventions in the observation field of the scanning device during the normal winding process have no effect as long as the normal winding layer level can still be observed. It has thus also when a flange enters eobachtungsfeld not influence the end of a winding layer in the B. Only when the observed winding layer level has disappeared in the last winding layer after laying the last turn, is the scanning device sensitized again in order to detect a new change. In this situation, the next one is expected change the upgrade is so that only upon detection of this process, the U msteuerungsprogramm triggered the first turn of the new winding position for the transition into the next winding layer. This achieves a very reliable reversal of the winding process during the transition to the next higher winding position, which is largely free of interference, which is an essential step in the goal of fully automating such winding processes.

Der Erfindung zufolge kann die Abtasteinrichtung eine tangential zum Wickel gerichtete Fernsehkamera sein. Alternativ kann der Erfindung zufolge die Abtasteinrichtung aus radial zur Spule gerichteten Entfernungssensoren, z.B. Ultraschallsensoren, bestehen. Schließlich kann der Erfindung zufolge auch vorgesehen werden, daß die Abtasteinrichtung aus einer radial auf die Spule gerichteten Fernsehkamera und einem demgegenüber geneigten, die Spule mit einem über den Wickelgutauflaufbereich sich erstreckenden Lichtband anstrahlenden'Scheinwerfer besteht.According to the invention, the scanning device can be a television camera directed tangentially to the winding. Alternatively, according to the invention, the scanning device can be made radial to the coil directed distance sensors, such as ultrasonic sensors. Finally, according to the invention, it can also be provided that the scanning device consists of a television camera directed radially onto the coil and a headlight which is inclined relative to it and illuminates the coil with a light strip extending over the winding material run-up area.

Die Erfindung wird im folgenden anhand mehrerer in der Zeichnung dargestellter Ausführungsbeispiele näher beschrieben, wobei in der Zeichnung zeigen:

The invention is described in more detail below with reference to several exemplary embodiments shown in the drawing, the drawing showing:
  • 1 shows a winding machine according to the invention in front view,
  • FIG. 2 the winding machine, seen in the direction of arrow II in FIG. 1,
  • FIGS. 3, 4 and 5 show sketches to explain an optoelectric winding scanning device,
  • FIGS. 6, 7 and 8 show sketches to explain an acoustoelectric winding scanning device, and
  • FIGS. 9, 10 and 11 are sketches for explaining a further embodiment of an optoelectric winding scanning device.

Die Figuren 1 und 2 veranschaulichen eine Wickelmaschine mit einem vierbeinigen, auf Rollen 1 verfahrbaren Gerüst 2, an dessen oberen Teil zwei Pinolenarme 3,4 aufgehängt sind, auf deren unteren Pinolen 5,6 eine Spule 7 mit Flanschen 8 aufgenommen ist. Der Spule 7 wird über einen ortsfest angeordneten Strangführer 9 ein strangförmiges Wickelgut 10 zugeführt, das mit eng aneinander anliegenden Windungen und mit exakt übereinander liegenden Wickellagen aufgewickelt werden soll. Während des Wickelvorganges wandert die Wickelgutauflaufstelle 11 zwischen den Spulenflanschen 8 hin und her, wobei zur Erzielung einer engen Anlage benachbarter Windungen das Wickelgut mit einem konstanten Auflaufwinkel auf die Spule auflaufen soll. Zur Aufrechterhaltung des Auflaufwinkels wird der Wickler beim Ausführungsbeispiel auf bodenseitigen Schienen vor dem Strangführer 9 mittels eines Vorschubantriebes 12 hin und her verfahren.FIGS. 1 and 2 illustrate a winding machine with a four-legged frame 2 that can be moved on rollers 1, on the upper part of which two quill arms 3, 4 are suspended, on the lower quills 5, 6 of which a coil 7 with flanges 8 is received. A coil-shaped winding material 10 is fed to the coil 7 via a strand guide 9 which is arranged in a stationary manner and which is to be wound up with closely adjacent turns and with winding layers lying exactly one above the other. During the winding process, the winding material run-up point 11 moves back and forth between the coil flanges 8, with a view to achieving a close fit position of adjacent turns, the material to be wound should run onto the spool with a constant run-up angle. To maintain the run-up angle, the winder in the exemplary embodiment is moved back and forth in front of the strand guide 9 by means of a feed drive 12.

Die Figuren 3 bis 5 veranschaulichen eine optoelektrische Abtasteinrichtung 13 in Form einer Fernsehkamera, welche hier etwa tangential zum Wickel gerichtet ist und einen Beobachtungsblickwinkel mindestens gleich der maximalen Bewicklungsdicke d der Spule besitzt. Die Kamera ist auf die Wickellagenstufe 14 zwischen zwei aufeinander folgenden Wickellagen ausgerichtet, und zwar an einer um 180° gegenüber der Wickelgutauflaufstelle 11 versetzten Stelle. Bei der Ausbildung der in Figur 3 gezeigten Wickellage wandert die Wickellagenstufe 14 zum linken Flansch 8 hin, während gleichzeitig die Spule 8 bzw. der Wickler 2 durch den Vorschubantrieb 12 nach rechts hin im Sinne auf Aufrechterhaltung eines konstanten Zulaufwinkels für das Wickelgut 10 bewegt wird. Sobald die Wickelstufe 14 bei Legen der letzten Windung dieser Lage verschwindet, wird die Abtasteinrichtung 13 in Bereitschaft geschaltet zur Erfassung einer neuen Wickellagenstufe 14'. Sobald diese neue Wickellagenstufe 14' erfaßt worden ist, liefert die Abtasteinrichtung 13 ein Signal an einen.programmierten Rechner 15, der ein vorgegebenes Umsteuerprogramm für den Changierantrieb 12 beim Übergang in die neue Wicklunglage einschaltet. Zur besseren Erfassung der Wickelgutstufen liegen der Fernsehkamera 13 auf der anderen Seite der Spule eine Kontrastfläche 16 gegenüber.FIGS. 3 to 5 illustrate an optoelectric scanning device 13 in the form of a television camera, which here is oriented approximately tangentially to the winding and has an observation angle of view at least equal to the maximum winding thickness d of the coil. The camera is aligned with the winding layer stage 14 between two successive winding layers, specifically at a point offset by 180 ° with respect to the winding material take-up point 11. In the formation of the winding layer shown in FIG. 3, the winding layer stage 14 moves toward the left flange 8, while at the same time the coil 8 or the winder 2 is moved to the right by the feed drive 12 in order to maintain a constant feed angle for the winding material 10. As soon as the winding stage 14 disappears when the last turn of this layer is laid, the scanning device 13 is switched to standby to detect a new winding layer stage 14 '. As soon as this new winding layer stage 14 'has been detected, the scanning device 13 delivers a signal to a programmed computer 15, which switches on a predetermined reversal program for the traversing drive 12 during the transition to the new winding position. For better detection of the winding levels, the television camera 13 has a contrast surface 16 on the other side of the coil.

Das Ausführungsbeispiel nach den Figuren 6 bis 8 zeigt eine akustoelektrische Abtasteinrichtung 17, welche beispielsweise aus Ultraschallsensoren aufgebaut ist, die radial auf den Wickel';gerichtet sind und über die Schallreflexion die Existenz der Wickellagenstufe 14 und das Aufsteigen einer neuen Wickellagenstufe 14' erfassen, wobei wiederum die Auswertung analog wie beim Ausführungsbeispiel nach den Figuren 3 bis 5 erfolgt.The exemplary embodiment according to FIGS. 6 to 8 shows an acoustoelectric scanning device 17, which is constructed, for example, from ultrasonic sensors which are directed radially onto the roll 'and, via sound reflection, the existence of the winding layer stage 14 and the ascent of a new winding layer stage 14 ', the evaluation again taking place analogously to the exemplary embodiment according to FIGS. 3 to 5.

Als weitere Alternative zeigen die Figuren 9 bis 11 eine optoelektrische Abtastung, welche aus einer etwa radial auf die Spule gerichteten Fernsehkamera 18 und aus einem demgegenüber geneigten Scheinwerfer 19 besteht, welcher die Spule 7 über ihre ganze Länge hinweg mit einem Lichtband 20a, 20b anstrahlt. Infolge der unterschiedlichen Ausrichtung von Scheinwerfer 19 und Kamera 18 verspringt für die Kamera das Lichtband an der Stufe zwischen zwei übereinanderliegenden Wickellagen und kann folglich also der Aufbau und das Wandern dieser Stufe von der Kamera 18 exakt verfolgt werden. Wenn die letzte Windung an dem Flansch anlangt, verschwindet der Lichtbandteil 20b, womit die Über wachungseinrichtung in Bereitschaft geschaltet wird, um danach das Auftreten des neuen, versetzten Lichtbandabschnittes 20b' zu erfassen.As a further alternative, FIGS. 9 to 11 show an optoelectric scanning, which consists of a television camera 18 directed approximately radially onto the coil and a headlight 19 which is inclined in relation thereto and which illuminates the coil 7 over its entire length with a light band 20a, 20b. As a result of the different alignment of the headlight 19 and the camera 18, the light band for the camera jumps on the step between two superimposed winding layers, and consequently the build-up and migration of this step can be followed exactly by the camera 18. When the last turn arrives at the flange, the light band part 20b disappears, whereby the monitoring device is switched to standby in order to then detect the occurrence of the new, offset light band section 20b '.
