Description

Die Erfindung bezieht sich auf Verfahren zur Herstellung von Transformatorkernen, die aus einer Vielzahl von abgestapelten Blechen gebildet sind, wobei die Bleche von einer Vorratsrolle kontinuierlich abgerollt, nachfolgend auf Länge und Form geschnitten, nach dem Schneiden über ein Transportbandsystem gefördert und auf einem Stapeltisch abgestapelt werden.The invention relates to methods for producing transformer cores, which are formed from a plurality of stacked sheets, wherein the sheets are unrolled from a supply roll continuously, subsequently cut to length and shape, conveyed after cutting over a conveyor belt system and stacked on a stacking table ,

Um Transformatorkerne herstellen zu können, werden bisher Blechpakete in einer Anlage schnittkantenunabhängig hintereinander abgelegt. Später werden die einzelnen relativ großen Bleche der Blechpakete zumeist durch zwei Personen von Hand zu einem Transformatorkern zusammengesetzt. Der Arbeits-und Zeitaufwand ist hierbei sehr hoch, wodurch die Kosten für die Herstellung eines Transformatorkerns ebenfalls relativ hoch sind.In order to be able to produce transformer cores, laminated cores have hitherto been deposited one after the other in a system independent of the cutting edges. Later, the individual relatively large sheets of laminated cores are usually assembled by two people by hand to form a transformer core. The labor and time is very high, whereby the cost of producing a transformer core are also relatively high.

Ein Verfahren zur Herstellung von Transformatorkernen gemäß Oberbegriff von Anspruch 1 ist in DE 3836790 sowie in DE 2613150 offenbart.A method for manufacturing transformer cores according to the preamble of claim 1 is in DE 3836790 as in DE 2613150 disclosed.

Der Erfindung liegt die Aufgabe zugrunde, Verfahren der angegebenen Gattung zu schaffen, bei denen komplette Transformatorkerne in E- und C-Form direkt von der Herstellungsanlage für die einzelnen Bleche hergestellt werden, wobei die Effizienz der gesamten Anlage bzw. bei der Herstellung von Transformatorkernen wesentlich erhöht ist und die Herstellkosten wesentlich reduziert sind.The invention has for its object to provide methods of the specified type, in which complete transformer cores in E and C shape are made directly from the manufacturing plant for the individual sheets, the efficiency of the entire system or in the production of transformer cores essential is increased and the production costs are substantially reduced.

Diese Aufgabe wird erfindungsgemäß durch Verfahren gemäß der Patentansprüche 1 bis 8 gelöst.This object is achieved by the method according to claims 1 to 8.

Die erfindungsgemäßen Verfahren zeichnen sich in erster Linie dadurch aus, dass sowohl einzelne Bleche und auch Pakete mit einer Mehrzahl von Blechen direkt zu einem Transformatorkern abgestapelt werden. Erst danach wird der jeweilige Stapeltisch in die nächste Position zum Abstapeln der nächsten Einzelbleche oder Blech-Pakete verfahren. Dadurch entsteht eine ernorme Zeitersparnis. Eine weitere Zeitersparnis wird dadurch erreicht, dass mehrere Stapeltische bzw. Stapeltische mit darauf befestigten Drehtischen vorgesehen sind, wodurch mehrere Transformatorkerne gleichzeitig hergestellt werden können.The inventive method is characterized primarily by the fact that both individual sheets and packages with a plurality of sheets are stacked directly to a transformer core. Only then is the respective stacking table moved to the next position for stacking the next individual sheets or sheet metal packages. This results in a tremendous time savings. A further time saving is achieved in that a plurality of stacking tables or stacking tables are provided with turntables mounted thereon, whereby multiple transformer cores can be produced simultaneously.

Bei den nachfolgend beschriebenen Verfahren zur Herstellung von Transformatorkernen 1, die aus einer Vielzahl von Blechen 2 - 6 gebildet sind, werden in einer Anlage die Bleche 2 - 6 von einer Vorratsrolle kontinuierlich abgerollt, nachfolgend auf Länge und Form geschnitten, nach dem Schneiden über ein Transportbandsystem gefördert und auf einem oder mehreren Stapeltischen 11 abgestapelt.In the method described below for the production of transformer cores 1, which are formed from a plurality of sheets 2 - 6, the sheets 2 - 6 are continuously unrolled from a supply roll in a plant, then cut to length and shape, after cutting over a Promoted conveyor belt system and stacked on one or more stacking tables 11.

Obwohl mit den Verfahren einzelne Bleche wie auch Pakete von Blechen abgestapelt werden können, sind nachfolgend zur Vereinfachung lediglich die Verfahren zur Abstapelung von Paketen von Blechen beschrieben.Although the methods can be used to stack individual sheets as well as packages of sheets, for simplification only the methods for stacking packages of sheet metal are described below.

Verfahren I zum vollautomatischen Abstapeln eines offenen E-Transformatorkerns:Method I for fully automatic unstacking of an open E-transformer core:

Bei einem ersten Verfahren (siehe hierzu insbesondere Fig. 3) werden in mindestens zwei in Förderrichtung der Bleche 2 - 6 hintereinander angeordneten Stapelstationen 12 zunächst wechselweise jeweils wechselweise eine Mehrzahl von Blechen einer Schenkelseite 2 bzw.4 des Transformatorkerns 1 auf den Stapeltischen 11 und eine Mehrzahl von Blechen einer Jochseite 5 bzw. 6 auf Ablagetischen 15 übereinander gestapelt. Solche abgestapelte Pakete aus Blechen 2 - 6 bestehen beispielsweise aus 3 - 14 Blechen. Nach dem seitlichen Verfahren der Stapeltische 11 werden in den Stapelstationen 12 wechselweise jeweils wechselweise eine Mehrzahl von Blechen der anderen Schenkelseite 4 bzw. 2 des Transformatorkerns 1 auf den Stapeltischen 11 und eine Mehrzahl von Blechen der anderen Jochseite 6 bzw. 5 in Aufnahmeeinrichtungen 13 übereinander gestapelt. Nach dem weiteren seitlichen Verfahren der Stapeltische 11 werden auf denselben wechselweise jeweils eine Mehrzahl von Blechen des Mittelschenkels 3 des Transformatorkerns 1 übereinander gestapelt, wobei gleichzeitig Handlingsysteme 14 die Pakete aus Blechen der einen Jochseite 6 bzw. 5 in die rechtwinklige Stellung zur Förderrichtung a drehen. Danach legen die Handlingsysteme 14 die Pakete aus Blechen der einen Jochseite 6 bzw. 5 mit ihren Enden an den einen Enden der Pakete der Bleche der Schenkelseiten 2, 4 bzw. der Pakete der Bleche des Mittelschenkels 3 auf den Stapeltischen 11 ab. Nach dem seitlichen Verfahren der Stapeltische 11 in die Ausgangsposition wiederholen sich die bis hier beschriebenen Verfahrenschritte bis zum Erreichen der Gesamthöhe des jeweiligen Transformatorkerns 1, der ein offener E-Transformatorkern (siehe Fig. 1) ist, auf dessen Schenkelseiten 2, 4 und dessen Mittelschenkel 3 später die Wicklungen aufgebracht werden. Erst danach werden von Hand die Bleche der anderen Jochseite 5 bzw. 6, die auf den Ablagetischen 15 zwischengestapelt wurden, an die Schenkelseiten 2, 4 und den Mittelschenkel 3 des E-Transformatorkerns 1 angelegt.In a first method (see in particular Fig. 3 ) are alternately in each case alternately a plurality of sheets of a leg side 2 bzw.4 of the transformer core 1 on the stacking tables 11 and a plurality of sheets of a yoke side 5 and 6 on tray tables in at least two in the conveying direction of the sheets 2-6 stacked stacking stations 12 15 stacked on top of each other. Such stacked packages of sheets 2 - 6 consist for example of 3 - 14 sheets. After the side processing of the stacking tables 11, a plurality of sheets of the other leg 4 and 2 of the transformer core 1 on the stacking tables 11 and a plurality of sheets of the other yoke 6 and 5 are alternately stacked in receiving devices 13 in the stacking stations 12, respectively , After the further lateral process of the stacking tables 11 are alternately stacked on the same alternately a plurality of sheets of the center leg 3 of the transformer core 1, wherein simultaneously handling systems 14, the packets of sheets of a yoke 6 and 5 rotate in the right-angled position to the conveying direction a. Thereafter, the handling systems 14 put the packets of sheets of a yoke side 6 and 5 with their ends to the an ends of the packets of the sheets of the leg sides 2, 4 and the packets of the sheets of the center leg 3 on the stacking tables 11 from. After the lateral movement of the stacking tables 11 into the starting position, the method steps described up to here are repeated until the total height of the respective transformer core 1, which has an open E-transformer core (see FIG Fig. 1 ), on whose leg sides 2, 4 and the middle leg 3 later the windings are applied. Only then are the sheets of the other yoke side 5 or 6, which were stacked on the tray tables 15, applied to the leg sides 2, 4 and the middle leg 3 of the E-transformer core 1 by hand.

Verfahren II zum vollautomatischen Abstapeln eines geschlossenen E-Transformatorkerns:Method II for fully automatic destacking of a closed E-transformer core:

Bei einem zweiten Verfahren (siehe auch hierzu insbesondere Fig. 3) werden ebenfalls in mindestens zwei in Förderrichtung (a) der Bleche hintereinander angeordneten Stapelstationen 12 zunächst wechselweise jeweils wechselweise eine Mehrzahl von Blechen einer Schenkelseite 2 bzw. 4 des Transformatorkerns 1 auf den Stapeltischen 11 und eine Mehrzahl von Blechen einer Jochseite 5 bzw. 6 in Aufnahmeinrichtungen 16 übereinander gestapelt. Nach dem seitlichen Verfahren der Stapeltische 11 werden hier jedoch in den Stapelstationen 12 wechselweise jeweils wechselweise eine Mehrzahl von Blechen der anderen Schenkelseite 4 bzw. 2 des Transformatorkerns 1 auf den Stapeltischen 11 und eine Mehrzahl von Blechen der anderen Jochseite 6 bzw. 5 in weiteren Aufnahmeeinrichtungen 13 übereinander gestapelt. Nach dem weiteren seitlichen Verfahren der Stapeltische 11 wird auf denselben wechselweise jeweils eine Mehrzahl von Blechen des Mittelschenkels 3 des Transformatorkerns 1 übereinander gestapelt, wobei gleichzeitig Handlingsysteme 14, 17 die Pakete aus Blechen der beiden Jochseiten 5 bzw. 6 in die rechtwinklige Stellung zur Förderrichtung a drehen. Danach legen die Handlingsysteme 14, 17 die Pakete aus Blechen der Jochseiten 5 bzw. 6 mit ihren Enden jeweils an den Enden der Pakete der Bleche der Schenkelseiten 2, 4 bzw. der Pakete der Bleche des Mittelschenkels 3 auf den Stapeltischen 11 ab. Auch hier wiederholen sich nach dem seitlichen Verfahren der Stapeltische 11 in die Ausgangsposition die bis hier beschriebenen Verfahrenschritte bis zum Erreichen der Gesamthöhe des jeweiligen Transformatorkerns 1, der dann ein geschlossener Transformatorkern (siehe auch Fig. 1) ist. Zum späteren Aufbringen der Wicklungen ist es hierbei jedoch notwendig, das obere Joch des Transformatorkerns zu entfernen und nach dem Aufbringen der Wicklungen wieder zu montieren.In a second method (see also this particular Fig. 3 are also in at least two in the conveying direction (a) of the sheets stacked stacking stations 12 initially alternately each alternately a plurality of sheets of a leg side 2 or 4 of the transformer core 1 on the stacking tables 11 and a plurality of sheets of a yoke side 5 and 6 in Receiving devices 16 stacked one above the other. However, according to the lateral process of the stacking tables 11, in the stacking stations 12, alternately a plurality of sheets of the other leg side 4 and 2 of the transformer core 1 are stacked on the stacking tables 11 and a plurality of sheets of the other yoke side 6 and 5 in other receiving means 13 stacked on top of each other. After the further lateral process of the stacking tables 11, a plurality of sheets of the center leg 3 of the transformer core 1 are alternately stacked on top of each other, wherein at the same time Handling systems 14, 17 rotate the packets of sheets of the two yoke sides 5 and 6 in the orthogonal position to the conveying direction a. Thereafter, the handling systems 14, 17 place the packets of sheets of the yoke sides 5 and 6 with their ends at the ends of the packets of the sheets of the leg sides 2, 4 or the packets of the sheets of the center leg 3 on the stacking tables 11. Here too, after the lateral movement of the stacking tables 11 into the starting position, the method steps described up to this point are repeated until the total height of the respective transformer core 1 is reached, which then becomes a closed transformer core (see also FIG Fig. 1 ). For later application of the windings, however, it is necessary in this case to remove the upper yoke of the transformer core and to mount it again after the windings have been applied.

Verfahren III zum vollautomatischen Abstapeln eines offenen C-Transformatorkerns:Method III for fully automatic destacking of an open C-transformer core:

Dieses dritte Verfahren, bei dem ein offener C-Transformatorkern abgestapelt wird (siehe Fig. 2), unterscheidet sich von dem ersten Verfahren lediglich dadurch, dass das Abstapeln des Mittelschenkels 3 entfällt. Ansonsten sind die Verfahrenschritte der beiden Verfahren identisch.This third method, in which an open C-transformer core is stacked (see Fig. 2 ), differs from the first method only in that the stacking of the center leg 3 is omitted. Otherwise, the process steps of the two methods are identical.

Verfahren IV zum vollautomatischen Abstapeln eines geschlossenen C-Transformatorkerns:Method IV for fully automatic destacking of a closed C-transformer core:

Das vierte Verfahren, bei dem ein geschlossener C-Transformatorkern abgestapelt wird, unterscheidet sich von dem zweiten Verfahren ebenfalls lediglich dadurch, dass das Abstapeln des Mittelschenkels 3 entfällt. Ansonsten sind die Verfahrenschritte der beiden Verfahren auch hier identisch.The fourth method, in which a closed C-transformer core is stacked, also differs from the second method only in that the stacking of the center leg 3 is omitted. Otherwise, the process steps of the two methods are identical here as well.

Auf mindestens zwei 21, 23 von mindestens vier 21, 22, 23, 24 in Förderrichtung a der Bleche 2 -6 hintereinander angeordneten, auf Stapeltischen befestigten Drehtischen wird bei einem fünften Verfahren zunächst wechselweise jeweils eine Mehrzahl von Blechen einer Schenkelseite 2 bzw. 4 des Transformatorkerns 1 übereinander gestapelt, wobei die beiden anderen Drehtische 22, 24 in die entsprechende Position verfahren und gedreht werden (Fig. 4a). Auch hier besteht ein solches abgestapeltes Paket aus beispielsweise 3 - 14 Blechen. Danach wird auf den beiden anderen Drehtischen 22, 24 wechselweise jeweils eine dem ersten Paket von Blechen entsprechende Mehrzahl von Blechen der einen Schenkelseite 2 bzw. 4 des Transformatorkerns 1 übereinander gestapelt, wobei die einen Drehtische 21, 23 jeweils seitlich in die Position zum Abstapeln der Bleche des Mittelschenkels 3 des Transformatorkerns 1 verfahren werden (Fig. 4b).

Auf den beiden anderen Drehtischen 22, 24 wird danach wechselweise jeweils eine dem ersten Paket von Blechen entsprechende Mehrzahl von Blechen der anderen Schenkelseite 4 bzw. 2 des Transformatorkerns 1 übereinander gestapelt, wobei die einen Drehtische 21, 23 jeweils in die Position zum Abstapeln der Bleche der jeweiligen einen Jochseite 5 bzw. 6 des Transformatorkerns 1 verfahren und gedreht werden (Fig. 4f). Anschließend wird auf den einen Drehtischen 21, 23 wechselweise jeweils eine dem ersten Paket von Blechen entsprechende Mehrzahl von Blechen der einen Jochseite 5 bzw. 6 des Transformatorkerns 1 übereinander gestapelt, wobei die anderen Drehtische 22, 24 jeweils seitlich in die Position zum Abstapeln der Bleche der jeweiligen einen Jochseite 5 bzw. 6 des Transformatorkerns 1 verfahren und gedreht werden (Fig. 4g). Auf den beiden anderen Drehtischen 22, 24 wird danach wechselweise jeweils eine dem ersten Paket von Blechen entsprechende Mehrzahl von Blechen der einen Jochseite 5, 6 des Transformatorkerns 1 übereinander gestapelt, wobei die einen Drehtische 21, 23 jeweils in die Position zum Abstapeln der Bleche der einen Schenkelseite 2 bzw. 4 des Transformatorkerns 1 verfahren und gedreht werden.

Verfahren VII zum vollautomatischen Abstapeln eines offenenMethod VII for fully automatic unstacking of an open C-Transformatorkerns:C-core transformer:

Dieses siebte Verfahren, bei dem nun wieder ein offener C-Transformatorkern abgestapelt wird (siehe Fig. 2), unterscheidet sich von dem fünften Verfahren lediglich wiederum dadurch, dass das Abstapeln des Mittelschenkels 3 entfällt. Ansonsten sind die Verfahrenschritte der beiden Verfahren identisch.This seventh method, in which now again an open C-transformer core is stacked (see Fig. 2 ), differs from the fifth method only in turn in that the destacking of the center leg 3 is omitted. Otherwise, the process steps of the two methods are identical.

Verfahren VIII zum vollautomatischen Abstapeln eines geschlossenen C-Transformatorkerns:Method VIII for fully automatic destacking of a closed C-transformer core:

Das achte Verfahren, bei dem ein geschlossener C-Transformatorkern abgestapelt wird, unterscheidet sich von dem sechsten Verfahren ebenfalls lediglich dadurch, dass das Abstapeln des Mittelschenkels 3 entfällt. Ansonsten sind die Verfahrenschritte der beiden Verfahren auch hier identisch.The eighth method, in which a closed C-transformer core is stacked, also differs from the sixth method only in that the stacking of the center leg 3 is omitted. Otherwise, the process steps of the two methods are identical here as well.

Es versteht sich von selbst, dass auch nur zwei oder mehr als zwei Stapeltische und/oder vier oder mehr als vier Drehtische vorgesehen sein können, wobei vorzugsweise eine gerade Anzahl von Tischen vorgesehen sein sollte, was wiederum die Effizienz weiter steigert.It goes without saying that only two or more than two stacking tables and / or four or more than four rotary tables can be provided, wherein preferably an even number of tables should be provided, which in turn further increases the efficiency.

Wie bereits erwähnt, ist es darüber hinaus möglich, mit den jeweiligen Verfahren auch einzelne Bleche, d.h. Blech für Blech zu dem jeweiligen Transformatorkern abzustapeln.As already mentioned, it is also possible to stack individual sheets, ie sheet by sheet, to the respective transformer core with the respective method.
