Description

Die Erfindung betrifft eine Mehrfach-Wickelmaschine gemäss dem Oberbegriff des Patentanspruchs 1.The invention relates to a multiple winding machine according to the preamble of patent claim 1.

Eine Mehrfach-Wickelmaschine, bei welcher ein Drahtführer sowohl für die eigentliche Bewicklung des Spulenkörpers als auch zum Andrillen von Drahtenden an radial zum Spulenkörper angeordnete Anschlussstifte vorgesehen ist, ist gemäss der deutschen Patentschrift DE 2 654 032 bekannt. Bei dieser Wickelmaschine ist auf einer gemeinsamen Trägerstange für jede ortsfest angeordnete Wickelspindel jeweils ein Drahtführer angeordnet. Durch eine Axialbewegung der Trägerstange sowie in Querrichtung dazu, als auch eine Schwenkbewegung kann nicht nur ein gleichzeitiges Wickeln mehrerer Spulen sondern auch ein Anwickeln der Drahtenden an Spulenkörper mit radial angeordneten Anschlussstiften vorgenommen werden. Demgegenüber eine Andrillung der Drahtenden an axial zum Spulenkörper angeordnete Anschlussstifte ist nicht möglich.A multiple winding machine, in which a wire guide is provided both for the actual winding of the coil former and for the twisting of wire ends onto connection pins arranged radially to the coil former, is known from German patent DE 2 654 032. In this winding machine, a wire guide is arranged on a common support rod for each stationary winding spindle. By means of an axial movement of the carrier rod and in the transverse direction thereto, as well as a pivoting movement, not only a simultaneous winding of several coils but also a winding of the wire ends onto the coil former with radially arranged connecting pins can be carried out. In contrast, the wire ends are not curled at connection pins arranged axially to the coil former.

Eine weitere deutsche Patentschrift DE-A-3 145 179, die als nächstliegender Stand der Technik angesehen wird, offenbart eine Mehrfach-Wickelmaschine zum Bewickeln von elektrischen Spulen mit mehreren im Abstand nebeneinander angeordneten Wickelspindeln und einem entlang der Wickelspindeln in der Längsachse der Wickelmaschine geführten Träger, auf welchem für jede Wickelspindel mindestens ein Drahtführungskopf angeordnet ist, wobei der Träger axial verschiebbar ist und quer zur Längsausdehnung kippbar ausgebildet ist. Für Spulenkörper mit radialen bzw. axialen Anschlussstiften ist eine innerhalb des schwenkbaren Drahtführers angeordnete Klemmrinrichtung vorgesehen, wobei bei Spulenkörpern mit axial angeordneten Anschlussstiften durch entsprechende Positionierung des Drahtführers ein Drahtabschnitt an den Anschlussstift ansetzbar und in dieser Lage von einem Fankhaken eines separaten Anwickelwerkzeuges erfassbar ist. Die Drahtführer mit bereits eingefädeltem Draht sind in einem Trägermagazin abgelegt, wobei der entsprechende Drahtführer mittels einer Trägerstange in das Magazin hinein- bzw.aus diesem in die Arbeitsstellung herausführbar ist.Another German patent DE-A-3 145 179, which is considered the closest prior art, discloses a multiple winding machine for winding electrical coils with a plurality of winding spindles arranged at a distance from one another and a carrier guided along the winding spindles in the longitudinal axis of the winding machine , on which at least one wire guide head is arranged for each winding spindle, the carrier being axially displaceable and designed to be tiltable transversely to the longitudinal extent. For coil bobbins with radial or axial connection pins, a clamping ring device arranged inside the pivotable wire guide is provided, with coil bobbins with axially arranged connection pins by appropriate positioning of the wire guide, a wire section can be attached to the connecting pin and can be grasped in this position by a fan hook of a separate winding tool. The wire guides with already threaded wire are stored in a carrier magazine, the corresponding wire guide being able to be guided into and out of the magazine into the working position by means of a carrier rod.

Bei einer derartigen Anordnung der Magazine ist ein relativ grosser Platzbedarf erforderlich und beim Zu- und Wegführen der Drahtführer kann es zu Störungen durch Berühren der geführten Drähte kommen.With such an arrangement of the magazines, a relatively large amount of space is required and, when the wire guides are fed in and out, malfunctions can occur due to touching the guided wires.

Gemäss der DE-A 3 609 896 ist weiterhin eine Wickelmaschine bekannt, bei welcher am Wickelschlitten in einer Ebene senkrecht zur Wickelspindel eine Drahtzuführungseinrichtung mit mindestens zwei Drahtführern bewegbar vorgesehen ist, wobei die Drahtzuführungseinrichtung in entsprechenden Drahtführungsstellungen verriegelbar ist, und dass den Drahtführern je eine elektrisch oder pneumatisch steuerbare Drahtbremse vorgelagert ist. Die Drahtzuführungseinrichtung samt den Drahtführern ist auf einem um einen Drehpunkt schwenkbaren Revolver aufgesetzt, wodurch ein Drahtwechsel möglich ist. Mittels der gelenkig ausgebildeten Drahtzuführungseinrichtung ist eine Verbindung der Drahtenden mit radial bis tangential am Spulenkörper angeordneten Anschlussstiften möglich.According to DE-A 3 609 896, a winding machine is also known, in which a wire feed device with at least two wire guides is provided on the winding slide in a plane perpendicular to the winding spindle, the wire feed device being lockable in corresponding wire guide positions, and the wire guides each being electrically or upstream pneumatically controllable wire brake. The wire feed device together with the wire guides is placed on a revolver which can be pivoted about a pivot point, as a result of which a wire change is possible. By means of the articulated wire feed device, it is possible to connect the wire ends to connecting pins arranged radially to tangentially on the coil former.

Ein Nachteil besteht hierbei insbesondere darin, dass die Drahtführer im Wickelbereich verbleiben und das herausragende Drahtende des in Warteposition befindlichen Drahtführers den Wicklungsablauf stören können. Ein weiterer Nachteil besteht darin, dass eine Verbindung der Drahtenden mit axial am Spulenkörper angeordneten Anschlussstiften nicht möglich ist.A disadvantage here is in particular that the wire guides remain in the winding area and the protruding wire end of the wire guide in the waiting position can disrupt the winding process. Another disadvantage is that it is not possible to connect the wire ends to connection pins arranged axially on the coil former.

Da für den überwiegenden Bedarf an derartigen elektrischen Spulen mit mehreren Wicklungen zwei verschiedene Wicklungsdrähte und/oder mit unterschiedlichen Drahtdurchmessern ausreichen, wird angestrebt, das umständliche Zu- und Wegführen der Drahtführer und den damit verbundenen technischen Aufwand zu verringern.Since two different winding wires and / or with different wire diameters are sufficient for the predominant need for such electrical coils with a plurality of windings, the aim is to carry out the cumbersome feeding and removal to reduce the wire guide and the associated technical effort.

Die Aufgabe der Erfindung besteht darin, ein schnelles Wechseln von zwei Drahtführern mit verschiedenen Wicklungsdrähten und/oder mit unterschiedlichen Drahtdurchmessern auf eine einfache Weise und platzsparend zu ermöglichen, wobei gleichzeitig ein gegenseitiges Berühren der Drähte ausgeschlossen sein soll,und dass ferner die Drahtenden mit radial bzw. axial zum Spulenkörper angeordneten Anschlussstiften ohne ein besonderes Anwickelwerkzeug verbunden werden können.The object of the invention is to enable a quick change of two wire guides with different winding wires and / or with different wire diameters in a simple manner and in a space-saving manner, wherein at the same time mutual contact of the wires is to be excluded, and furthermore the wire ends with radial or can be connected axially to the coil body connecting pins without a special winding tool.

Die vorgenannte Aufgabe wird durch die kennzeichnenden Markmale des Patentanspruchs 1 gelöst. Weitere Ausbildungen des Erfindungsgegenstandes gehen aus den abhängigen Ansprüchen hervor.The above object is achieved by the characterizing features of claim 1. Further developments of the subject matter of the invention emerge from the dependent claims.

Die erfindungsgemässe Ausbildung der auf einem Träger angeordneten, beispielsweise sechs Drahtführungsköpfen mit je zwei zueinander versetzten, schwenkbaren Drahtführern, ermöglicht bei bisher gleich grosser Wickelspindel-Teilung eine extrem platzsparende Anordnung, ohne jeweils den Arbeitsbereich der Wickelvorrichtung einzuschränken.The inventive design of the arranged on a carrier, for example six wire guide heads, each with two mutually offset, swiveling wire guides, allows an extremely space-saving arrangement with previously identical winding spindle pitch without restricting the working range of the winding device.

Der Vorteil der Erfindung besteht insbesondere darin, dass für die Bewicklung von Spulen, bei denen die Drahtführer in ihrer Warteposition längere, störungsanfällige Drahtenden aufweisen, diese durch die Drahtführungsköpfe bei der Schwenkung der Drahtführer jeweils aus der Wickelposition in die Warteposition gleichzeitig auf die zum Erfassen erforderliche minimale Länge zurückgezogen werden, so dass ein störungsfreier Wickelablauf gewährleistet ist.The advantage of the invention is, in particular, that for winding coils in which the wire guides have longer, fault-prone wire ends in their waiting position, these are simultaneously moved through the wire guide heads when the wire guides are pivoted from the winding position into the waiting position to the one required for detection minimum length must be withdrawn so that a trouble-free winding process is guaranteed.

Dadurch, dass jeweils ein Drahtführer in Wickelposition und der andere unmittelbar dazu in Warteposition geschwenkt ist, ist eine schnelle Umstellung der Drahtführer aus der Warteposition in die Wickelposition und umgekehrt gewährleistet.The fact that one wire guide is swiveled into the winding position and the other is swiveled directly into the waiting position, rapid changeover of the wire guides from the waiting position to the winding position and vice versa is guaranteed.

Eine Drahtklemmeinrichtung ermöglicht eine automatische Einstellung der Drahtklemmung sowohl für Spulenkörper mit radial als auch axial angeordneten Anschlussstiften, so dass sich ein Umrüsten bzw. ein besonderes Anwickelwerkzeug erübrigt.A wire clamping device enables automatic setting of the wire clamping both for bobbins with radially and axially arranged connecting pins, so that a changeover or a special winding tool is unnecessary.

Die Erfindung wird nachfolgend anhand der in den Zeichnungen dargestellten Ausführungsbeispielen im einzelnen erläutert.The invention is explained in detail below on the basis of the exemplary embodiments illustrated in the drawings.

In Fig.1 (und teilweise in den Fig.2, 2a, 2b) ist eine Wickelvorrichtung einer aus mehreren, beispielsweise sechs Wickelvorrichtungen bestehender Mehrfach-Wickelmaschine zum Bewickeln von elektrischen Spulen mit 10 bezeichnet. Auf einer Grundplatte 11 ist auf einem Ständer 13 ein Revolverkopf 12 mit in Halterungen 14, 14′ in Wickelachsen 15, 15′ geführten Wickelspindeln angeordnet, wobei ein unbewickelter Spulenkörper 52 aus der Beschickungs-/Entnahme-Position C durch Drehen des Revolverkopfes 12 um dessen Hochachse in die Wickelposition A und gleichzeitig eine bereits bewickelte Spule 54 in die Entnahme-/Beschickungsposition C geschwenkt wird.In FIG. 1 (and partly in FIGS. 2, 2a, 2b), a winding device of a multiple winding machine consisting of several, for example six, winding devices for winding electrical coils is designated by 10. On a base plate 11 is a turret 13 on a stand 12 arranged in brackets 14, 14 'in winding axes 15, 15' guided winding spindles, an unwound bobbin 52 from the loading / unloading position C by rotating the turret 12 about its vertical axis into the winding position A and at the same time an already wound bobbin 54 is pivoted into the removal / loading position C.

In der Längsausdehnung der Wickelmaschine 10 ist ein kippbar ausgebildeter Träger 20 vorgesehen, auf dem für jede Wickelvorrichtung ein Drahtführungskopf 30, 30′ mit mindestens einer Trenneinrichtung 17, 17′ zusammenwirkend angeordnet ist. Jeder Drahtführungskopf 30, 30′ weist mehrere, vorzugsweise zwei Drahtführer 31, 31′ auf, so dass Spulen 54 mit verschiedenen Wickeldrähten 50, 50′ und/oder unterschiedlichen Drahtstärken hergestellt werden können, ohne die Wickelmaschine jeweils umrüsten zu müssen. Der Träger 20 zusammen mit den Drahtführungsköpfen 30, 30′ und den Trenneinrichtungen 17, 17′ ist in frei programmierbaren X-, Y- und Z-Achsen bewegbar, wobei der Träger 20 mit den Drahtführungsköpfen 30, 30′ zum Andrillen der Drahtenden schwenkbar und die Trenneinrichtungen 17, 17′ zusätzlich vertikal oder horizontal verschiebbar ausgebildet sind.In the longitudinal extent of the winding machine 10, a tiltable support 20 is provided, on which a wire guide head 30, 30 'with at least one separating device 17, 17' is arranged cooperatively for each winding device. Each wire guide head 30, 30 'has several, preferably two wire guides 31, 31', so that coils 54 with different winding wires 50, 50 'and / or different wire thicknesses can be produced without having to retool the winding machine in each case. The carrier 20 together with the wire guide heads 30, 30 'and the separators 17, 17' can be moved in freely programmable X, Y and Z axes, the carrier 20 with the wire guide heads 30, 30 'being able to be pivoted to the wire ends and the separators 17, 17 'are also vertically or horizontally displaceable.

An einer an der Grundplatte 11 angeordneten Halterung 18 ist eine Drahtklemmeinrichtung 40 vorgesehen, die aus einer mit ausgezogenen Linien dargestellten Arbeitsposition in eine strichliert dargestellte Draht-Freigabe-Position, vorzugsweise um 135° schwenkbar ausgebildet ist.On a bracket 18 arranged on the base plate 11, a wire clamping device 40 is provided, which is designed to be pivotable by 135 ° from a working position shown in solid lines to a wire release position shown in broken lines.

Der Träger 20 ist gemäss Fig. 2 an einer Seite durch einen oder an beiden Seiten durch je einen Pneumatikzylinder 29 axial verschiebbar ausgebildet, und je nach Anzahl der im Abstand auf dem Träger 20 nebeneinander angeordneten Wickelspindeln sind für jede derselben Drahtführungsköpfe 30 vorgesehen. Jeder Drahtführungskopf 30 weist zwei Drahtführer 31, 31′ auf und ist mittels eines Stiftes 33 in eine Bohrung 21 des Trägers 20 einsetzbar. Durch Betätigung des bzw. der Pneumatikzylinder 29 wird der Drahtführer 31 bzw. 31′ aus seiner Wickelposition A in die Warteposition B und/oder umgekehrt geschwenkt. Die Positionierung des Drahtführungskopfes 30, 30′ erfolgt jeweils durch einen Anschlagstift 39, dessen horizontale Bewegung durch eine, in einer Führungsnut 25 des Trägers 20 gebildeten Aussparung 23 durch Anschlagflächen 24, 24′ begrenzt ist. Im Bereiche des Stiftes 33 an der Drahtführungs-Aussenfläche ist in einer muldenförmigen Aussparung eine Drahtöse 34 zur Einführung der Wickeldrähte 50, 50′ vorgesehen.2, the carrier 20 is designed to be axially displaceable on one side by one or on both sides by a pneumatic cylinder 29, and depending on the number of winding spindles arranged next to one another on the carrier 20, 30 are provided for each of the same wire guide heads. Each wire guide head 30 has two wire guides 31, 31 'and is by means of a pin 33 in a bore 21 of the carrier 20 can be used. By actuating the pneumatic cylinder or 29, the wire guide 31 or 31 'is pivoted from its winding position A into the waiting position B and / or vice versa. The positioning of the wire guide head 30, 30 'takes place in each case by a stop pin 39, the horizontal movement of which is limited by a recess 23 formed in a guide groove 25 of the carrier 20 by stop faces 24, 24'. In the area of the pin 33 on the wire guide outer surface, a wire eyelet 34 is provided in a trough-shaped recess for introducing the winding wires 50, 50 '.

Gemäss der Fig. 2, 2a und 2b sind am Drahtführungskopf 30, 30′ jeweils zwei Drahtklemmer 35, 35′ angeordnet, die an deren, dem Träger 20 zugewandten Innenfläche entsprechende Hebestifte 36, 36′ aufweisen, die durch einen Pneumatikzylinder 27 betätigbar sind. Der in Fig. 2 unmittelbar zum Pneumatikzylinder 29 angeordnete Drahtführungskopf 30 ist ohne seine Klemmer 35, 35′ dargestellt, um die Hebestifte 36, 36′ ersichtlich zu machen, wobei die Hebestifte 36, 36′ zum Träger 20 in die Längsausnehmung 22 im Bereiche des Pneumatikzylinders hinausragen. Eine in einer Nut 26 des Trägers 20 geführte Druckleitung 26′ sichert die Druckluft-Zuführung für den Pneumatikzylinder 27 zum Anheben jeweils eines der Drahtklemmer 35, 35′ mittels der Hebestifte 36, 36′ gegen die Kraft einer Druckfeder 37, 37′. Der dem in Wickelposition A befindlichen Drahtführer 31, 31′ zugeordnete Drahtklemmer 35, 35′ wird durch den Hebestift 36, 36′ angehoben, so dass der Wickeldraht 50, 50′ ungebremst auf den Spulenkörper 52 aufgewickelt werden kann; während dem in Warteposition B befindlichen Drahtführer 31′, 31 zugeordnete Drahtklemmer 35′, 35 mit seinem Hebestift 36′, 36 ausserhalb des Pneumatikzylinders 27 zu liegen kommt, so dass der Wickeldraht 50′, 50 festgeklemmt bleibt.2, 2a and 2b, two wire clamps 35, 35 'are arranged on the wire guide head 30, 30', which have corresponding lifting pins 36, 36 'on their inner surface facing the carrier 20, which can be actuated by a pneumatic cylinder 27. 2 arranged directly to the pneumatic cylinder 29 wire guide head 30 is shown without its clamps 35, 35 'to make the lifting pins 36, 36' visible, the lifting pins 36, 36 'to the carrier 20 in the longitudinal recess 22 in the area of Protrude pneumatic cylinder. A in a groove 26 of the carrier 20 pressure line 26 'secures the compressed air supply for the pneumatic cylinder 27 for lifting one of the wire clamps 35, 35' by means of the lifting pins 36, 36 'against the force of a compression spring 37, 37'. The wire guide 31, 31 'in the winding position A' associated with the wire clamp 35, 35 'is raised by the lifting pin 36, 36' so that the winding wire 50, 50 'can be wound on the spool 52 without braking; while in the waiting position B the wire guide 31 ', 31 associated wire clamp 35', 35 with its lifting pin 36 ', 36 comes to lie outside the pneumatic cylinder 27, so that the winding wire 50', 50 remains clamped.

Entsprechend der bewickelnden Spule 54 kann das Drahtende derart abgetrennt werden, dass dieser zum Erfassen nur geringfügig aus dem Drahtführer 31,31′ herausragt oder im grösseren Abstand zu diesem abgetrennt werden muss, so dass das aus dem Drahtführer 31,31′ herausragende Drahtende durch Berühren der Wickeldrähte Störungen verursachen könnte.
