Description

Die vorliegende Erfindung betrifft eine Vorrichtung zum selbsttätigen Schichten von lamellierten Eisenkernen für Transformatoren und Drosselspulen, mit Vorratsmagazinen für Blechzuschnitte, mit wenigstens einem horizontal verschiebbaren Stapelmagazin, mit einem über den Magazinen horizontal verfahrbaren Transportwagen, an dem ein- und ausschaltbare Heber angebracht sind, mit Antrieben zum Verfahren des Transportwagens und zum Heben und Senken der Heber, sowie mit Endkontakten zur sicheren Ablaufsteuerung des Schichtvorgangs.The present invention relates to a device for the automatic layering of laminated iron cores for transformers and choke coils, with storage magazines for sheet metal blanks, with at least one horizontally displaceable stacking magazine, with a transport carriage which can be moved horizontally above the magazines and to which lifters which can be switched on and off are fitted with drives for moving the transport trolley and for lifting and lowering the lifters, as well as with end contacts for safe sequence control of the shifting process.

Das Stapeln der Kernblechpakete von Transformatoren und Drosselspulen mit der Hand ist aufwendig und unfallträchtig. Es hat nicht an Versuchen gefehlt, den Schichtvorgang maschinell zu erledigen. Die bekannten Schichtvorrichtungen besitzen Magazine zur Aufnahme der zu schichtenden Blechzuschnitte sowie Magazine zur Aufnahme der zusammengesetzten Kernpakete.Stacking the core laminated core of transformers and choke coils by hand is complex and prone to accidents. There has been no lack of attempts to do the shifting process mechanically. The known layer devices have magazines for recording the sheet metal blanks to be layered and magazines to hold the assembled core packages.

Eine bekannte Vorrichtung besitzt beispielsweise je ein Magazin zur Aufnahme der E-förmigen und der I-förmigen Blechzuschnitte. Aus diesen Magazinen wird das jeweils unterste Blech entnommen und mit Hilfe von Schiebern in den auf dem Vorratsmagazin liegenden Spulenkörper geschachtelt.A known device has, for example, a magazine for receiving the E-shaped and the I-shaped sheet metal blanks. The bottom sheet in each case is removed from these magazines and nested with the aid of sliders in the coil former lying on the supply magazine.

Es ist weiterhin eine Vorrichtung zum Schichten von Eisenkernen für Transformatoren und Drosselspulen aus Einzelblechen bekannt, bei der im Bereich der Enden der Arme eines zentral gelagerten Drehkranzes oder Drehsterns Greifelemente enthaltende Blechhubeinheiten angebracht sind, mit denen von Vorratsstapeln in einer oder mehreren Lagen in der Kernform zusammengelegte Bleche abhebbar und nach einer Drehung des Drehkreuzes auf den an einer anderen Stelle des Drehkranzes befindlichen Schichttisch wieder auflegbar sind. Die Greiferelernente der Blechhubeinheiten können durch Sauger oder durch E1 ktromagnete verkörpert sein. Außerdem sind die Sauger oaer Elektromagnete in vertikaler Richtung elastisch verschiebbar angeordnet. Die Greiferelemente sind so in unterschiedlicher Höhe angeordnet, daß das abzuhebende Blech zuerst definiert in einem Endbereich angehoben wird und der so eingeleitete Abhebevorgang sich über die ganze Blechlänge hinweg gleichmäßig fortsetzt. Auf diese Weise können die zwischen den aufeinanderliegenden Blechen wirkenden Adhäsions- und Reibungskräfte überwunden und ein sicheres Abheben der obersten Blechlage gewährleistet werden. Zusätzlich können im Bereich der Stirnseiten der Blechstapel Spreizmagnete angesetzt werden, die ein Auffächern der oberen Blechlagen bewirken. Das von den Greiferelementen des Drehkranzes erfaßte oberste Blech wird nach einer Drehung des Drehkranzes auf einem Schichttisch, wo die Bleche mit H.ilfe von Stehbolzen während des Schichtvorgangs fixiert werden, abgelegt.Furthermore, a device for layering iron cores for transformers and choke coils from single sheets is known, in which sheet lifting units containing gripping elements are attached in the region of the ends of the arms of a centrally mounted turntable or rotating star, with which stacked stacks of the core form are put together in one or more layers Sheets can be lifted off and, after rotating the turnstile, placed on the shift table located at another location on the turntable. The gripper elements of the sheet metal lifting units can be embodied by suction devices or by E1 ktromagnets. In addition, the suction cups or electromagnets are arranged to be elastically displaceable in the vertical direction. The gripper elements are arranged at different heights so that the sheet to be lifted is first lifted in a defined area in an end region and the lifting process thus initiated continues uniformly over the entire length of the sheet. In this way, the adhesive and frictional forces acting between the sheets lying on top of each other can be overcome and a safe lifting of the top sheet layer can be ensured. In addition, spreading magnets can be attached in the area of the end faces of the sheet metal stack, which cause the upper sheet metal layers to fan out. The top sheet, gripped by the gripper elements of the slewing ring, is after a Rotation of the slewing ring on a shift table, where the sheets are fixed with the help of stud bolts during the shift process.

Es ist weiterhin ein Verfahren zum Schichten lamellierter Eisenkerne für Transformatoren und Drosselspulen größerer Leistung bekannt, bei welchem in einem Arbeitsvorgang mittels einer Greiferplatte, an der in vertikaler Richtung elastisch verschiebbar angeordnete, ein- und ausschaltbare Elektromagnete oder Saugdüsen sitzen, eines der aufgestapelten Bleche von einem der Vorratstische abgenommen und ein im vorhergehenden Arbeitsgang in gleicher Weise von einen anderen Vorratstisch abgenommenes Blech auf dem Schichttisch stets an der gleichen Stelle abgelegt wird. Die Greiferplatte ist zu diesem Zweck horizontal verfahr-und vertikal verschiebbar. Zur automatischen Steuerung der Horizontal- und Vertikaloewegungen des Schichttisches sowie der Greiferelemente besitzt die bekannte Vorrichung Endkontakte, die sowohl an der Greiferplatte als auch an den Vorrats- und Schichttischen angeordnet sein können. Zum weiteren Transport der fertigen Eisenkerne ist der Schichttisch als rollenbahn ausgebildet. Um die Stapelführungs- und Ausrichtelemente anbringen zu können, sind die Vorratstische als Lochplatten ausgebildet. Ferner sind auf den Vorratstischen dem Kernprofil entsprechende, verstellbare Anschlagleisten angeordnet, die mittels Bolzen befestigt und nach Drehung um die Bolzen aus den fertig magazinierten Blechstapeln herausnehmbar sind. Der Schichttisch ist mittels eines weiteren Elektromotors in vertikaler Richtung verschiebbar. und ermöglicht damit, daß die Oberflächen aller Stapel während des gesamten Schichtvorganges immer in einer Flucht liegen.Furthermore, a method for layering laminated iron cores for transformers and choke coils of higher power is known, in which one of the stacked sheets of one is located in one working process by means of a gripper plate on which electromagnets or suction nozzles that are arranged to be elastically displaceable in the vertical direction can be switched on and off the supply table is removed and a sheet removed from another supply table in the previous operation is always placed in the same place on the shift table. For this purpose, the gripper plate can be moved horizontally and vertically. For the automatic control of the horizontal and vertical movements of the shift table and the gripper elements, the known device has end contacts which can be arranged both on the gripper plate and on the supply and shift tables. The layer table is designed as a roller conveyor for further transport of the finished iron cores. In order to be able to attach the stacking and aligning elements, the storage tables are designed as perforated plates. Furthermore, adjustable stop strips corresponding to the core profile are arranged on the supply tables, which are fastened by means of bolts and can be removed from the finished stacked sheets after rotation about the bolts. The shift table can be moved in the vertical direction by means of a further electric motor. and thus enables the surfaces of all stacks to always be in alignment during the entire layering process.

Das Verfahren sowie das Heben und Senken der Greiferolatte, das Aufnehmen der Bleche von den Vorratstischen und das Ablegen auf cem Schichttisch sowie das nach Ablegen jeden Bleches erfolgende Absenken des Schichttisches um eine Blechdicke erfolgt so lange, bis die vorgesehene Schichthöhe des Magnetkerns erreicht ist. Anschließend wird der Kernstapel auf der Rollenbahn weggerollt und ein neuer Stapelvorgang beginnt.The process, as well as the lifting and lowering of the gripper bar, the picking up of the sheets from the supply tables and placing them on the shift table, as well as the lowering of the shift table by a sheet thickness after each sheet has been carried out, is continued until the intended layer height of the magnetic core is reached. The core stack is then rolled away on the roller conveyor and a new stacking process begins.

Bei dieser bekannten Vorrichtung ist nachteilig, daß die Blechstapel auf den Vorratstischen sowie auf dem Schichttisch stets gleiches Niveau besitzen müssen, so daß die Höhe des Schichttisches einstellbar sein muß, daß nur jeweils ein Magnetkern aus den auf zwei Vorratstischen gestapelten Blechzuschnitten aufgebaut wird, daß der Schichtvorgang unterbrochen werden muß, sobald ein Kernstapel fertiggestellt ist, so daß der gesamte Schichtvorgang relativ langsam abläuft.In this known device it is disadvantageous that the stack of sheets on the supply tables and on the shift table must always have the same level, so that the height of the shift table must be adjustable so that only one magnetic core is built up from the sheet metal blanks stacked on two supply tables, that the The layering process must be interrupted as soon as a core stack is completed, so that the entire layering process proceeds relatively slowly.

Der vorliegenden'Erfindung liegt deshalb die Aufgabe zugrunde, eine Vorrichtung zum selbsttätigen Schichten von lamellierten Eisenkernen der eingangs genannten Art dahingehend zu verbessern, daß ein gleichzeitiges Schichten mehrerer Kernstapel aus den in mehreren Magazinen enthaltenen Blechzuschnitten möglich ist, daß ein unterbrechungsfreies Schichten möglich ist, und daß die Vorratsmagazine jederzeit mit beliebigen Mengen von Blechen gefüllt sein können.The present invention is therefore based on the object of improving a device for the automatic layering of laminated iron cores of the type mentioned in such a way that a simultaneous layering of a plurality of core stacks from the sheet metal blanks contained in several magazines is possible, that an uninterrupted layering is possible, and that the storage magazines can be filled with any amount of sheets at any time.

Diese Aufgabe wird dadurch gelöst, daß die Anzahl der Vorratsmagazine der Anzahl der zu schichtenden Blechzuschnitte entspricht, daß die Vorratsmagazine in wenigstens einer Reihe hintereinander angeordnet sind, daß die Stapelmagazine hintereinander auf einem endlosen Transport- band angeordnet sind, und daß ein taktweise arbeitender Antrieb für das Transportband vorhanden ist.This object is achieved in that the number of storage magazines corresponds to the number of sheet metal blanks to be layered, that the storage magazines are arranged one behind the other in at least one row, that the stacking magazines are arranged one behind the other on an endless conveyor belt, and that a cyclically operating drive for the conveyor belt is present.

Damit ergeben sich die Vortoile, daß gleichzeitig eine Vielzahl von gleichartigen Kernstapeln geschichtet werden kann, daß der Schichtvorgang durch die Entnahme der fertigen Kernstapel nicht unterbrochen wird, daß die Entnahme aus den Stapelmagazinen außerhalb des Schichtbereiches erfolgt, daß die Zahl der Heb- und Senkvorgänge der Heberelemente reduziert ist, da sie nur noch zum Aufnehmen der Bleche aus den Vorratsmagazinen abgesenkt werden, während zum Ablegen die Bleche frei in die Stapelmagazine fallen, und daß der die Heber horizontal verfahrende Transportwagen selbst nicht gehoben und gesenkt wird.This results in the advantages that a large number of identical core stacks can be layered at the same time, that the layering process is not interrupted by the removal of the finished core stack, that the removal from the stacking magazines takes place outside the layer area, that the number of lifting and lowering operations of the Lifter elements is reduced, since they are only lowered to take up the sheets from the storage magazines, while the sheets fall freely into the stacking magazines for depositing, and that the transport carriage itself, which moves horizontally, is not raised and lowered.

Vorzugsweise sind die Vorratsmagazine in zwei Reihen hintereinander angeordnet, laufen die Stapelmagazine zwischen den Vorratsmagazinen, entspricht die Anzahl der Stapelmagazine wenigstens der Anzahl der Paare von Vorratsmagazinen, sind die ein- und ausschaltbaren Heber an beiden Enden des Transportwagens befestigt und sind die jeder Reihe von Vorratsmagazinen zugeordneten Reihen von Hebern unabhängig voneinander heb- und senkbar.The storage magazines are preferably arranged in two rows one behind the other, the stacking magazines run between the storage magazines, the number of stacking magazines corresponds at least to the number of pairs of storage magazines, the lifters which can be switched on and off are fastened to both ends of the transport carriage and are the ones of each row of storage magazines assigned rows of jacks can be raised and lowered independently of each other.

Durch diese Weiterbildung kann die Baulänge der selbsttätigen Stapelvorrichtung auf die Hälfte reduziert werden. Gleichzeitig wird der Schichtvorgang weiter dadurch beschleunigt, daß bei jedem Verfahren des Transportwagens Bleche aus den Vorratsmagazinen aufgenommen, sowie Bleche in die Stapelmagazine abgelegt werden.With this development, the overall length of the automatic stacking device can be reduced by half. At the same time, the layering process is further accelerated in that sheets are taken from the storage magazines each time the trolley is moved, and sheets are deposited in the stacking magazines.

Vorzugsweise sind die Heber als Saugdüsen oder als Elektromagnete ausgebildet.The lifters are preferably designed as suction nozzles or as electromagnets.

Gemäß einer vorteilhaften Weiterbildung sind an jedem Vorratsmagazin feste und bewegliche Anschläge vorgesehen, um die Magazine auf unterschiedlich große Blechzuschnitte einstellen zu können. Vorzugsweise sind die beweglichen Anschläge'aller Vorratsmagazine einer Reihe gemeinsam verstellbar, wodurch die Einstellarbeiten weiter verkürzt werden können.According to an advantageous development, fixed and movable stops are provided on each storage magazine in order to place the magazines on sheet metal blanks of different sizes to be able to adjust. The movable stops of all the storage magazines in one row are preferably adjustable jointly, as a result of which the adjustment work can be further shortened.

Vorteilhafterweise sind die Saugdüsen einzeln lageverstellbar. Auf diese Weise können in jedem Vorratsmagazin beliebig geformte Blechzuschnitte gelagert werden, so wie es vom Stapelvorgang her technisch bedingt ist, und gleichzeitig ist ein sicheres Eingreifen und Abheben der obersten Blechlage möglich..The suction nozzles are advantageously individually adjustable in position. In this way, sheet metal blanks of any shape can be stored in each storage magazine, as is technically necessary for the stacking process, and at the same time a secure engagement and lifting of the uppermost sheet layer is possible.

Vorzugsweise sind die Saugdüsen in vertikaler Richtung frei beweglich. Sie werden beim Heben des Saugdüsenhalters von ihrem Gewicht in die jeweils unterste Position gezogen,-so daß das abzulegende Blech jeweils dieselbe Höhe über dem Stapelmagazin hat. Federn wie beim Stand der Technik sind nicht erforderlich.The suction nozzles are preferably freely movable in the vertical direction. When the suction nozzle holder is lifted, they are pulled from their weight into the lowest position, so that the sheet to be put down has the same height above the stacking magazine. Springs as in the prior art are not required.

Die Stapelmagazine sind vorzugsweise auf einem Kettenförderer befestigt und laufen in einer endlosen Schleife durch die Schichtvorrichtung.The stacking magazines are preferably fastened on a chain conveyor and run in an endless loop through the layer device.

Besonders vorteilhaft ist, wenn jedes Stapelmagazin auf seinem Förderband in zwei Ebenen gegen die Waagerechte geneigt ist. Gleichzeitig ist auf jedem Stapelmagazin ein fester Winkelanschlag so befestigt, daß dessen Spitze an der am tiefsten liegenden Ecke des Magazins liegt. Auf diese Weise wird erreicht, daß die beim Ablegen frei fallenden Bleche jeweils mit einer Ecke in den Anschlagwinkel rutschen, so daß alle übereinander geschichteten Bleche die gewünschte räumliche Position zueinander und übereinander besitzen.It is particularly advantageous if each stacking magazine is inclined on its conveyor belt in two planes against the horizontal. At the same time, a fixed angle stop is attached to each stacking magazine so that its tip lies at the deepest corner of the magazine. In this way it is achieved that the sheets that fall freely when put down each slide with a corner into the stop angle, so that all the sheets stacked one above the other have the desired spatial position with respect to one another and one above the other.

Gemäß einer vorteilhaften Weiterbildung ist jedem Vorratsmagazin ein Belegungswächter zugeordnet, der verhindert, daß die Maschine auch dann weiterläuft, wenn das Bedienungspersonal vergessen hat, Blechzuschnitte nachzulegenAccording to an advantageous development, each supply magazine is assigned an occupancy monitor which prevents the machine from continuing to run even if the operating personnel have forgotten to add sheet metal blanks

Vorzugsweise sind den Saugdüsen Vakuumwächter zugeordnet. Diese Vakuumwächter sprechen sofort an, wenn eine der Saugdüsen einmal kein Blech erfaßt oder wenn das Blech wieder herabfällt. Das fehlende Blech kann dann vom Bedienungspersonal von Hand nachgelegt werden.Vacuum monitors are preferably assigned to the suction nozzles. These vacuum monitors respond immediately if one of the suction nozzles does not catch any sheet or if the sheet falls down again. The missing sheet can then be added manually by the operating personnel.

In einer weiteren Ausbildung der erfindungsgmäßen Vorrichtung kann auch der Entnahmestation der Stapelmagazine ein Belegungswächter zugeordnet sein. Mit Hilfe des Belegungswächters können Störungen der Maschine, die durch eine Stockung bei der Entnahme der fertigen Kernstapel entstehen können, sicher vermieden werden. Hierzu wird der Schichtvorgang so lange unterbrochen, bis das an der Entnahmestation stehende Vorratsmagazin geleert ist.In a further embodiment of the device according to the invention, an occupancy monitor can also be assigned to the removal station of the stack magazines. With the help of the occupancy monitor, malfunctions of the machine, which can occur due to a stagnation during the removal of the finished core stack, can be safely avoided. For this purpose, the layering process is interrupted until the storage magazine at the removal station is emptied.

Vorzugsweise ist jede Reihe von Saugdüsen mittels Hydraulikzylindern, insbesondere Druckluftzylindern, unabhängig heb- und senkbar. Diese Maßnahme hat eine Verringerung der bewegten Massen zur Folge, wodurch der Schichtvorgang beschleunigt werden kann.Each row of suction nozzles can preferably be raised and lowered independently by means of hydraulic cylinders, in particular compressed air cylinders. This measure results in a reduction in the moving masses, which means that the layering process can be accelerated.

In vorteilhafter Weise ist der Transportwagen über einen Exzenterantrieb verfahrbar. Der Exzenterantrieb wird über ein Untersetzungsgetriebe von einem Elektromotor angetrieben. Statt durch einen Exzenter kann das Verfahren des Transportwagens auch durch einen Preßluftzylinder, einen Hydraulikzylinder oder einen elektrischen Linearmotor erfolgen.The transport carriage can advantageously be moved via an eccentric drive. The eccentric drive is driven by an electric motor via a reduction gear. Instead of using an eccentric, the trolley can also be moved using a compressed air cylinder, a hydraulic cylinder or an electric linear motor.

Gemäß einer vorteilhaften Weiterbildung sind jedem Vorratemagazin Spreizmagnete zugeordnet. Diese Spreizmagnete bewirken, daß die in den Vorratsmagazinen liegenden Blechzuschnitte sich an ihrer Vorderkante gegenseitig abstoßen, wodurch das Abnehmen des obersten Blechs vom Blechstpel erleichtert wird.According to an advantageous further development, spreading magnets are assigned to each storage magazine. These spreading magnets cause the sheet metal blanks lying in the storage magazines to repel each other at their front edge, which makes it easier to remove the top sheet from the sheet pile.

Anhand der Zeichnung soll die Erfindung in Form eines Ausführurngsbeispiels näher erläutert werden.The invention will be explained in more detail in the form of an exemplary embodiment with reference to the drawing.

Fig. 1 zeigt eine Draufsicht auf eine automatisch arbeitende Schichtvorrichtung mit zwei Reihen von Vorratsmagazinen, zwischen denen die Stapelmagazine laufen.Fig. 1 shows a plan view of an automatically operating stratification device with two rows of storage magazines, between which the sta p elma g azine run.

Fig. 2 zeigt eine Frontansicht der Vorrichtung.Fig. 2 shows a front view of the device.

Man erkennt einen Rahmen aus vier senkrecht stehenden Trägern 1.1, Längsträgern 1.2, oberen Querträgern 1.3 und zwei unteren Querträgern 1.4. Auf den unteren Querträgern 1.4 sind in Längsrichtung weitere Träger 2 befestigt, die an ihrer Oberseite je eine Reihe von Vorratsmafatinen 3, 4 tragen. Zwischen den beiden Reihen von Vorratsmagazinen 3, 4 verlaufen die auf einem endlosen Transportband 6 angeordneten Stapelmagazine 5.One can see a frame made up of four vertical beams 1.1, longitudinal beams 1.2, upper cross beams 1.3 and two lower cross beams 1.4. On the lower cross beams 1.4 further beams 2 are fastened in the longitudinal direction, each carrying a row of storage mafatins 3, 4 on their upper side. The stacking magazines 5 arranged on an endless conveyor belt 6 run between the two rows of storage magazines 3, 4.

Der Vorschub der Stapelmagazine 5 erfolgt taktweise mit Hilfe eines Antriebsmotors 7.The stack magazines 5 are fed in cycles with the aid of a drive motor 7.

Im Bereich der oberen Querträger 1.3 sind Laufschienen 12 angeordnet, auf denen ein Transportwagen 8 horizontal verschiebbar läuft. Der Transportwagen 8 wird über einen von einem Elektromotor 13 und ein Untersetzungsgetriebe 14 angetriebenen Exzenter 15 zwischen seinen beiden Endstellungen verschoben. Am Transportwagen 8 sind weiterhin Hydraulikzylinder 16 befestigt, die jeweils eine Reihe von Saugdüsen 9, 10 heben und senken.In the area of the upper cross member 1.3, rails 12 are arranged, on which a transport carriage 8 runs horizontally. The transport carriage 8 is displaced between its two end positions via an eccentric 15 driven by an electric motor 13 and a reduction gear 14. Hydraulic cylinders 16, which each raise and lower a row of suction nozzles 9, 10, are also attached to the transport carriage 8.

Die Saugdusen 9, 10 sind relativ zum Transportwagen 8 so eirgestellt., daß in der einen Endstellung des Transportvagens 8 die Saugdüsen 9 über den Vorratsmagazinen 3, die Saugdüsen 10 über den Stapelmagazinen 5 stehen, während in der anderen Endstellung des Transportwagens die Saugdüsen 10 über den Vorratsmagazinen 4, die Saugdüsen 9 über den Stapelmagazinen 5 stehen. Es sind so viele Saugdüsen 9, 10 vorgesehen, wie Vorratsmagazine 3, 4, wobei im gezeichneten Beispiel jeweils zwei Saugdüsen zu einer Einheit gehören. An den oberen Enden der Saugdüsen 9, 10 sind (in der Zeichnung nicht dargestellte) flexible Schläuche angeordnet, die zu einer,(ebenfalls nicht gezeichneten) Vakuumsammelleitung führen, die die Verbindung zu einer Vakuumpumpe herstellt.The suction nozzles 9, 10 are so created relative to the transport carriage 8 that in one end position of the transport carriage 8 the suction nozzles 9 are above the storage magazines 3, the suction nozzles 10 are above the stacking magazines 5, while in the other end position of the transport carriage the suction nozzles 10 are above the storage magazines 4, the suction nozzles 9 are above the stacking magazines 5. There are as many suction nozzles 9, 10 as storage magazines 3, 4, two suction nozzles belonging to one unit in the example shown. At the upper ends of the suction nozzles 9, 10 (not shown in the drawing) flexible hoses are arranged, which lead to a (also not shown) vacuum manifold, which establishes the connection to a vacuum pump.

Die auf dem Förderband 6 befestigten Stapelmagazine 5 sind in zwei Ebenen geneigt, so daß die von den Saugdüsen freigegebenen Bleche immer in die am tiefsten liegende Ecke gegen einen festen Winkelanschlag 17 fallen.The stacking magazines 5 fastened on the conveyor belt 6 are inclined in two planes, so that the sheets released by the suction nozzles always fall into the deepest corner against a fixed angular stop 17.

Die Vorratsagazine 3, besitzen jeweils einen festen Winkel Anschlag 18, sowie einen beweglichen Winkelanschlag 19. Die beweglichen Anschläge 19 jeder Reihe von Vorratsmagazinen 3 bzw. 4 sind mit Hilfe eines Handrades 20 und einer Gewindestange 21 gemeinsam verstellbar, um eine Anpassung an unterschiedlich große Magnetkerne zu ermöglichen.The storage magazines 3 each have a fixed angular stop 18 and a movable angular stop 19. The movable stops 19 of each row of storage magazines 3 and 4 can be adjusted together by means of a handwheel 20 and a threaded rod 21 in order to adapt to differently sized magnetic cores to enable.

Anhand der Figur 2 soll die Funktion der gezeigten Vorrichtung erläutert werden. In der gezeichneten Endstellung des Transportwagens 8 werden die Saugdüsen 9 mit Hilfe der linken Hydraulikzylinder 16 auf die in den Vorratsmagazinen befindlichen Bleche 11 abgesenkt. Da die Saugdüsen 9 in ihren Führungen 22 frei beweglich sind, können unterschiediiche Hoben der Blechetapel 11 ausgeglichen werden. Anschließend werden die Saugdüsen 9 angehoben bis in die gezeichnete Stellung und der Transportwagen 8 in seine rechte Endstellung geschoben. Nunmehr befinden sich die Saugdüsen 9 über den Stapelmagazinen 5 in der Position, ie zuvor die Saugdüsen 10 eingenommen hatten, während sich die Saugdüsen 10 jetzt in der angedeuteten Position 10' über den Vorratsmagezinen 4 befinden. In diesem Momont wird das Vakuum der sich jetzt in der Mitte befindenden Saugdüsen 9 abgeschaltet, so daß die Bleche frei in die Stapelmagazine 5 gegen den festen Anschlagwinkel 17 fallen. Gleichzeitig werden die Saugdüsen 10' abgesenkt und ergreifen die obersten Blechlagen in den Vorratsmagazinen 4, worauf sich der eben beschriebene Vorgang wiederholt. Die Vorratsmagazine 4 bewegen sich schrittweise vorwärts, wobei der Vorschub nach jedem Ablegen einer Blechreihe oder aber nach jeden zweiten Ablegen einer Blechreihe erfolgen kann. Da die Anzahl der Vorratsmagazine gleich ist der Anzahl der Blechzuschnitte pro zu schichtendem Kernstapel und die Zahl der Saugdüseneinheiten gleich ist der Zahl der Vorratsmagazine, werden die Kernstapel taktweise während des Durchlaufs durch die Beschichtungszone der erfindungsgemäßen Verrichtung kontinuierlich fertiggestellt und können an einer außerhalb der eigentlichen Schichtzone liegenden Entnahmestation 23 entnommen werden, ohne daß der Schichtvorgang selbst dabei gestört wird.The function of the device shown will be explained with reference to FIG. In the drawn end position of the transport carriage 8, the suction nozzles 9 are lowered onto the sheets 11 located in the storage magazines by means of the left hydraulic cylinders 16. Since the suction nozzles 9 are freely movable in their guides 22 are different lifting of the sheet stack 11 can be compensated. Then the suction nozzles 9 are raised to the position shown and the trolley 8 is pushed into its right end position. The suction nozzles 9 are now located above the stacking magazines 5 in the position that the suction nozzles 10 had previously occupied, while the suction nozzles 10 are now in the indicated position 10 'above the storage magazines 4. In this moment, the vacuum of the suction nozzles 9 now in the middle is switched off, so that the sheets fall freely into the stacking magazines 5 against the fixed stop angle 17. At the same time, the suction nozzles 10 'are lowered and grip the uppermost sheet layers in the storage magazines 4, whereupon the process just described is repeated. The storage magazines 4 move forward step by step, the feed being able to take place after each placement of a row of sheets or after every second placement of a row of sheets. Since the number of supply magazines is equal to the number of sheet metal blanks pr o schichtendem core stack and the number of suction nozzle is equal to the number of storage bins, the core stacks are cyclically completed continuously through the coating zone of performing the invention during the passage and can at one outside of the actual Removal station 23 lying layer zone are removed without the layering process itself being disturbed.

Die Lage der in der Zeichnung nicht dargestellten Endschalter, Vakuumwächter und Bewegungswächter kann anhand der geschilderten Funktionen leicht vom Fachmann selbst ermittelt werden.The position of the limit switches, vacuum monitors and motion monitors (not shown in the drawing) can easily be determined by a person skilled in the art using the functions described.
