Abstract

The invention relates to a bandaging system, consisting of a curved needle, of a special needle guide and of a special needle attachment arm and its drive. The bandaging system, which is extended to form a complete bandaging device, is used for the automated bandaging of winding overhangs of electrical machines. The problem of previous bandaging machines which bandage using straight needles moving at right angles with respect to the stator axis into the intermediate spaces of the winding overhangs is that the needles can easily perforate the stator stack or, if they are at some distance therefrom, no longer grip the wires which rest closely against the stator end laminate. This problem has been solved by the invention of a bandaging needle which is curved in a circular shape and of a drive and needle guide matched thereto. As a result of its circular shape and its movement on a circular arc this needle is at a sufficient distance from the stator laminate edge even though it slightly touches the stator end laminate, and hence grips all the wires, in the region of the winding overhang intermediate space.

Eine derartige Vorrichtung zum Bandagieren von Wicklungsköpfen, die aus in Nuten von Statorkörpern elektrischer Maschinen eingelegten Wicklungsspulen gebildet werden, ist aus der DE-PS 12 03 873 bekannt. Such a device for bandaging winding heads that made of winding coils inserted in the slots of stator bodies of electrical machines are formed is known from DE-PS 12 03 873. Der Statorkörper mit dem herausragenden Wicklungskopf wird mit einer von einer Vorratsspule ablaufenden Schnur maschinell unter fortlaufender Verschlingung von Schlaufen, die von einem Fadenabheber und von der Nadel gebildet werden, schrittweise umschnürt. The stator body with the protruding winding head is fitted with a Cord running off a supply reel by machine under continuous looping of loops that are formed by a thread lifter and the needle, step by step laced around. Bei diesen Vorrichtungen und Bandagiereinrichtungen, die mit geraden Nadeln bandagieren, welche senkrecht in bezug auf die Statorachse in die Zwischenräume der Wicklungsköpfe fahren und die Schnur mit dem Öhr der Nadel beim Durchstechen des Wicklungskopfzwischenraumes zur Innenseite des Wicklungskopfes bringen, hat sich gezeigt, daß das Einstechen der geraden Nadel erhebliche Schwierigkeiten bereitet. In these devices and bandaging devices with straight Bandage needles, which are perpendicular with respect to the stator axis in the interstices the winding heads drive and the cord with the eye of the needle when piercing of the winding head gap to the inside of the winding head has it has been shown that the piercing of the straight needle causes considerable difficulties. Folgende Schwierigkeiten sind festzustellen: Ist der eingestellte Abstand zwischen dem Statorendblech und der Nadel klein, so sticht die Nadel oft in die Statorbleche. Ist der eingestellte Abstand zwischen dem Statorendblech und der Nadel groß, so werden beim Einstechen der Nadel oft einzelne Drähte der Wick- lungsspule nicht erfaßt, also mit der Schnur nicht einbandagiert, insbesondere bei niedrigen Wicklungsköpfen. Bei Statorpaketen, die mittels mehrerer Klammern zusammengehalten werden, welche über das Statorendblech hinausragen, wird ein Einstechen der geraden Nadel in die Zwischenräume des Wicklungskopfes behindert oder sogar unmöglich gemacht. The following difficulties can be identified: Is the set The distance between the stator end plate and the needle is small, so the needle often sticks in the stator laminations. Is the set distance between the stator end plate and the needle is large, so when the needle is pierced, individual wires of the winding lung coil not captured, so not bandaged with the cord, especially at low levels Winding heads. In the case of stator assemblies that are held together by means of several clamps which protrude beyond the stator end plate, a piercing of the straight Needle in the gaps of the winding head obstructed or even made impossible. Auch ein Formvorgang mit Stützfingern, die in die Zwischenräume des Wicklungskopfes eingeführt werden und die Zwischenräume für die Nadel öffnen, bringt oft nicht den gewünschten Erfolg, weil die Elastizität des Drahtes teilweise die Zwischenräume wieder verschließt. Also a molding process with support fingers, which are inserted into the spaces between the The winding head are inserted and open the gaps for the needle, brings often not the desired result, because the elasticity of the wire is partly the Gaps closed again. Die Aufgabe der Erfindung ist daher mit folgenden Punkten beschrieben: a) Die Bandagiernadel soll mit genügend Abstand an den Halteklammern vorbeiführen. The object of the invention is therefore described with the following points: a) The bandaging needle should lead past the retaining clips with sufficient distance. b) Die Nadel soll im Bereich des Wicklungskopfquerschnittes 4 das Statorendblech berühren, um damit alle Drähte für die Bandage zu erfassen.b) The needle should be in the area of the winding head cross section 4 Touch the stator end plate to capture all of the wires for the drum. c) Die Nadel soll das Statorpaket nicht beschädigen.c) The needle should not damage the stator package. Die aufgezeigten Aufgaben werden erfindungsgemäß durch die kennzeichnenden Merkmale des Anspruchs 1 gelöst. According to the invention, the identified objects are replaced by the characterizing Features of claim 1 solved. Die Abstimmung des Radius der Nadel mit der Länge des Nadelbefestigungsarms und des Einspannwinkels der Nadel bewirkt eine Bewegung der Nadel auf einem Kreisbogen während des Bandagiervorgangs. Läßt man die Nadel, durch genaue Positionierung des Statorpaketes, das Statorendblech im Bereich des Wicklungskopfquerschnittes 4 berühren, so werden damit alle vom Wicklungskopf nach innen abstehenden Drähte noch erfaßt, und alle weiter entfernten Punkte des Statorendbleches 3, sowie auch die Klammern 8, haben genügend Abstand zur Nadel. Ein Einstechen der Nadel in das Statorpaket ist dadurch ausgeschlossen. Matching the radius of the needle with the length of the needle mounting arm and the clamping angle of the needle causes the needle to move on an arc of a circle during the bandaging process. If you let the needle, by precisely positioning the Stator core, touch the stator end plate in the area of the end winding cross section 4, in this way, all wires protruding inward from the winding head are still captured, and all further distant points of the stator end plate 3, as well as the brackets 8, have enough distance to the needle. Insertion of the needle into the stator package is therefore excluded. Ein Ausführungsbeispiel der Erfindung wird durch die Zeichnung F i g. 1 dargestellt und nachstehend näher erläutert. An embodiment of the invention is illustrated by the drawing F i g. 1 and explained in more detail below. Ein Nadelbefestigungsarm 19, der in die Bandagiervorrichtung integriert ist, ist in einem Lager 14 schwenkbar gelagert. Die Auf- und Abbewegung des Nadelbefestigungsarms geschieht durch den Antrieb, bestehend aus einer mit konstanter Winkelgeschwindigkeit drehenden Kurbel 9, dem in der Schwinge 11 laufenden Gleitstein 10, der schwenkbar gelagerten Schwinge 11 und der Lasche 12 zur gelenkigen Verbindung von Nadelbefestigungsarm 19 und Schwinge 11. A needle mounting arm 19 which is integrated into the bandaging device is, is pivotably mounted in a bearing 14. The up and down movement of the needle mounting arm happens through the drive consisting of a constant angular velocity rotating crank 9, the sliding block 10 running in the rocker 11, which is pivotable mounted rocker 11 and the tab 12 for the articulated connection of the needle mounting arm 19 and swing arm 11. Der Nadelbefestigungsarm 19 hat aus Gründen der Stabilität eine seitliche Führung 18. In der Einspannung 17 ist die Nadel 1 mittels Schrauben verspannt. Die Nadel 1 selbst hat einen konstanten Außen- und Innenradius und im Einspannbereich einen rechteckigen Querschnitt 2.The needle mounting arm 19 has a lateral one for reasons of stability Guide 18. In the fixture 17, the needle 1 is clamped by means of screws. the Needle 1 itself has a constant outer and inner radius and in the clamping area a rectangular cross-section 2. Damit die Nadel 1 mit der Kante 6 einen Kreisbogen beschreiben kann, ist der Nadelaußenradius der Länge des Nadelbefestigungsarmes 19 anzupassen, und die Nut der Einspannung 17 zur Aufnahme der Nadel 1 muß den gleichen Außenradius aufweisen wie die Nadel 1.So that the needle 1 can describe an arc with the edge 6, the outer needle radius is to be adapted to the length of the needle fastening arm 19, and the groove of the clamping 17 for receiving the needle 1 must have the same outer radius like needle 1.
