Description
Die Erfindung betrifft ein Verfahren zum Isolieren von Formspulen, bei dem mittels eines Automaten ein streifenförmiges Isoliermaterial um die Leiterbündel der Formspulen gewickelt wird.The invention relates to a method for isolating shaped coils, in which a strip-shaped machine is used Insulating material wrapped around the bundle of conductors of the form coils becomes.
Mit auf dem Markt befindlichen Automaten für das Aufbringen von Isolierbändern auf die Leiterbündel von Formspulen können die Formspulen nur dann von dem Automaten bewickelt werden, wenn die Formspulen die von dem Automaten vorgegebenen Mindestbearbeitungsgrößen hinsichtlich der Breite zwischen den Spulenseiten und/oder des von den Spulenschenkeln gebildeten Spreizwinkels aufweisen. Diese Mindestbearbeitungsgrößen liegen hinsichtlich der Spulenbreite bei 150-170 mm und hinsichtlich des Spreizwinkels bei größer/gleich 90°. Der Einbau der Formspulen in eine elektrische Maschine erfordert jedoch häufig Spulenabmessungen, die kleiner als die von den Automaten vorgegebenen Mindestgrößen sind. Ein derartiger Automat ist in dem Dokument FR-A-2 639 625 beschrieben.With automatic dispensers on the market from insulating tapes to the bundles of form coils the form coils are only wound by the machine, if the form coils are those specified by the machine Minimum machining sizes in terms of width between the coil sides and / or that formed by the coil legs Have spread angle. These minimum machining sizes are 150-170 mm in terms of spool width and with respect to the spread angle at 90 ° or greater. Of the Installation of the form coils in an electrical machine required however, coil dimensions are often smaller than those of the Vending machines are predetermined minimum sizes. Such a machine is described in document FR-A-2 639 625.
Der Erfindung liegt die Aufgabe zugrunde, ein Verfahren anzugeben, mit dem Formspulen unabhängig von den durch den Einbau in eine elektrische Maschine vorgegebenen Maßen mittels eines Automaten mit Isoliermaterial bewickelt werden können.The invention has for its object to provide a method with the form coils regardless of those by the installation dimensions specified in an electrical machine by means of a Machines can be wrapped with insulating material.
Die Lösung der gestellten Aufgabe gelingt nach der Erfindung dadurch, daß die Formspulen hinsichtlich ihrer Breite und/oder ihres von den Spulenschenkeln gebildeten Spreizwinkels entsprechend der durch den Automaten vorgegebenen Bearbeitungsgrößen vergrößert werden und nach dem Aufbringen des Isoliermaterials so verformt werden, daß sich die für den Einbau in eine elektrische Maschine erforderliche Breite der Spule und/oder der erforderliche Spreizwinkel einstellt. The problem is solved according to the invention in that the form coils in terms of their width and / or their spreading angle formed by the coil legs according to the one given by the machine Processing sizes are enlarged and after application of the insulating material are deformed so that the Installation in an electrical machine required width of the Sets the coil and / or the required spread angle.
Durch eine solche Vergrößerung der Spulenbreite und/oder des Spreizwinkels ist die Möglichkeit geschaffen, die Formspulen vollständig durch einen Automaten mit Isoliermaterial zu bewickeln. Durch die nachträgliche Verformung erhalten die Formspulen die für ihren Einbau in eine elektrische Maschine erforderlichen Maße.By such an increase in the coil width and / or Spreading angle is created, the form coils completely by a machine with insulating material wrap. The subsequent deformation gives them Form coils for their installation in an electrical machine required dimensions.
Die Formspulen können von vornherein mit einer Spulenbreite und/oder einem Spreizwinkel, welche jeweils den Mindestbearbeitungsgrößen des Automaten entsprechen, hergestellt und nach dem Isoliervorgang auf die für den Einbau in eine elektrische Maschine erforderlichen Abmessungen geformt werden.The form spools can be designed with a spool width and / or a spreading angle, each of which is the minimum machining size of the machine correspond, manufactured and after the insulation process on the for installation in an electrical Machine required dimensions are molded.
Liegen die Formspulen bereits mit den für den Einbau in eine elektrische Maschine erforderlichen Abmessungen vor, dann können diese Formspulen vor dem Aufbringen des Isoliermaterials entsprechend der durch den Automaten vorgegebenen Mindestbearbeitungsgrößen aufgeweitet werden.Are the form coils already with those for installation in a electrical machine required dimensions before, then can use these coils before applying the insulating material according to the one given by the machine Minimum processing sizes are expanded.
Zweckmäßigerweise erfolgt das Aufweiten und/oder Zurückformen der Spulen direkt durch den das Isoliermaterial aufwickelnden Automaten.The expansion and / or reshaping expediently takes place of the coils directly through the one winding the insulation material Machines.
Durch das angegebene Verfahren wird die Möglichkeit geschaffen, Formspulen unabhängig von der Größe ihrer Spulenbreite bzw. ihres Spreizwinkels vollständig durch einen Automaten mit einem Isolierband zu bewickeln. Durch die Vergrößerung des Spreizwinkels wird für das den Aufwickelvorgang ausführende Organ des Automaten auch an der Kröpfungsstelle der Stirnseite ausreichend Platz geschaffen, so daß dieses Organ die Bewicklung der Kröpfungsstelle durchführen kann. Desgleichen wird durch die Vergrößerung der Spulenbreite das Bewickeln der Spulenseiten auch bei Formspulen ermöglicht, die ansonsten gar nicht mittels eines Automaten bewickelt werden könnten.The specified procedure creates the possibility Form coils regardless of the size of their coil width or their spreading angle completely by a machine to wrap with an insulating tape. By enlarging of the spreading angle is used for the winding process Organ of the machine also at the point of cranking Front side created enough space so that this organ can carry out the winding of the offset. The same becomes by increasing the coil width Allows winding of the coil sides even with form coils, which are not otherwise wound by a machine could become.
Die Formspulen können von vornherein mit einem für die Bewicklung durch den Automaten ausreichend großen Spreizwinkel bzw. ausreichender Spulenbreite hergestellt werden. Nach dem Bewickeln mit Isoliermaterial werden die Spulen dann in die für den Einbau in eine elektrische Maschine erforderliche endgültige Form und Größe gebracht.The form spools can be used from the start with one for winding sufficiently wide spreading angle due to the machine or sufficient spool width. After this The coils are then wound into the required for installation in an electrical machine final shape and size.
Die Formspulen können aber auch bereits mit den für den Einbau in eine elektrische Maschine notwendigen Maßen hergestellt werden. Für das automatische Bewickeln werden solche Spulen dann entsprechend aufgeweitet. Eine solche Vorfertigung der Spulen in ihrer endgültigen Form ist insbesondere dann von Vorteil, wenn der Spreizwinkel bzw. die Spulenbreite der endgültigen Form bereits nahe bei den Mindestbearbeitungsgrößen des Automaten liegt. Die Spulen können dann aufgrund der ihnen innewohnenden Elastizität entsprechend aufgeweitet werden, ohne daß es zu einer bleibenden Verformung kommt. Damit federt die Formspule nach dem Bewickeln praktisch wieder in ihre endgültige Form zurück, ohne daß es einer wesentlichen Rückverformung bedarf.The form coils can also be used for installation dimensions required in an electrical machine become. For the automatic winding such Coils then expanded accordingly. Such prefabrication the coils in their final form is special then advantageous if the spreading angle or the coil width the final shape is close to the minimum machining sizes of the machine. The coils can then due to the inherent elasticity be expanded without causing permanent deformation is coming. The coil thus springs after winding practically back to its final form without it a substantial recovery is required.
Das Aufweiten und/oder Zurückformen kann durch entsprechende Vorrichtungen an den das Isolierband aufwickelnden Automaten erfolgen. Damit erübrigt sich ein Umsetzen der Formspulen auf gesonderte Geräte, mit denen die entsprechende Formung der Spulen vorgenommen werden müßte.The expansion and / or reshaping can be done by appropriate Devices on the machines winding up the insulating tape respectively. This eliminates the need to move the form coils separate devices with which the appropriate shaping of the Coils would have to be made.
