Description

Die Erfindung bezieht sich auf einen Bundwagen zum Fördern von Blechbunden mit einem Hubtisch, in dem eine Bundauflage um eine vertikale Achse drehbar gelagert und über einen Antrieb verschwenkbar ist.The invention relates to a coil carriage for conveying sheet metal coils with a lifting table in which a coil support is rotatably mounted about a vertical axis and can be pivoted via a drive.

Fördervorrichtungen für Blechbunde bestehen häufig aus zwei oder mehreren Bundwagen, die miteinander gekuppelt und zwischen ortsfesten Bundablagen verfahrbar sind. Die von einem Kran od. dgl. an der Aufgabestelle auf der Bundablage abgesetzten Bunde werden durch Anheben des Hubtisches des ersten Bundwagens von der Bundablage abgehoben und zur nächsten Bundablage gefahren, wo sie durch ein Senken des Hubtisches wieder abgesetzt werden. Kehren die-Bundwagen in ihre Ausganslage zurück, so befindet sich der erste Wagen wieder im Bereich der Aufgabestelle, während der zweite Wagen unterhalb des abgesetzten Bundes steht. Durch ein Anheben des Hubtisches des zweiten Wagens und ein wiederholtes Verfahren der Bundwagen kann somit eine Reihe von Bunden zwischen einer Aufgabestelle und einer Bearbeitungsanlage von Ablage zu Ablage weitergefördert werden. Da zur Weiterverarbeitung der Bleche die Bunde üblicherweise abgewickelt werden und der Abwickelsinn zufolge der Haspelkonstruktion festgelegt ist, müssen die Bunde in einer bestimmten Weise vom Haspel übernommen werden. Wird folglich ein Bund an der Aufgabestelle falsch orientiert abgelegt, so muß er, um den Abwickelsinn des Haspels beibehalten zu können, um 180° gedreht werden, damit die zunächst in Förderrichtung weisende Stirnseite des Bundes entgegen der Förderrichtung zeigt. Zu diesem Zweck wird der Bund durch ein Hebezeug erfaßt, gewendet und wieder abgelegt. Dieses Wenden der Blechbunde erfordert aber - nicht nur einen zusätzlichen Arbeitsaufwand, sondern bringt auch die zusätzliche Gefahr einer Bundbeschädigung mit sich. Außerdem kann nur mit aufwendigen Mitteln gewährleistet werden, daß der Bund wieder an der gleichen Stelle abgesetzt wird. Die mittige Lage des Bundes auf den einzelnen Bundablagen wird daher gefährdet, was Lagekorrekturen erforderlichen macht.Conveyors for sheet metal coils often consist of two or more coil wagons that are coupled to one another and can be moved between stationary coil shelves. The bundles set down by a crane or the like at the loading point on the bundle tray are lifted from the bundle tray by lifting the lifting table of the first bundling carriage and moved to the next bundling tray, where they are set down again by lowering the lifting table. When the coil wagons return to their starting position, the first wagon is again in the area of the drop-off point, while the second wagon is below the offset bund. By lifting the lifting table of the second carriage and repeating the movement of the coil carriage, a number of bundles between a loading point and a processing system can thus be conveyed from rack to rack. Since the bundles are usually unwound for further processing of the sheets and the direction of unwinding is determined according to the reel construction, the bundles have to be removed from the reel in a certain way be taken over. If, therefore, a bundle is placed incorrectly at the point of application, it must be rotated by 180 ° in order to be able to maintain the unwinding of the reel, so that the end face of the bundle pointing initially in the conveying direction points against the conveying direction. For this purpose, the federal government is gripped by a hoist, turned and put down again. This turning of the metal coils does not only require additional work, but also entails the additional risk of damage to the collar. In addition, it can only be ensured with elaborate means that the federal government is placed again in the same place. The central position of the federal government on the individual federal repositories is therefore endangered, which makes position corrections necessary.

Der Erfindung liegt somit die Aufgabe zugrunde, diese Mängel zu vermeiden und einen Bundwagen der eingangs geschilderten Art so zu verbessern, daß ein einfaches Wenden der Bunde ohne Beschädigungsgefahr und ohne zusätzliche Lagekorrekturen gewährleistet wird.The invention is therefore based on the object to avoid these deficiencies and to improve a coil carriage of the type described in such a way that a simple turning of the bundles is ensured without risk of damage and without additional position corrections.

Die Erfindung löst die gestellte Aufgabe dadurch, daß die Bundauflage um 180° verschwenkbar und vorzugsweise über den Steg eines Umlaufgetriebes antreibbar ist, das aus einem drehfest mit der Bundauflage verbundenen Zentralrad, einem am Steg gelagerten Umlaufrad und einem mit dem Umlaufrad kämmenden, am Hubtisch angeordneten, innen verzahnten Zahnkranzsegment besteht.The invention solves this problem in that the collar support is pivotable by 180 ° and can preferably be driven via the web of an epicyclic gear, which consists of a central wheel rotatably connected to the collar support, an epicyclic gear mounted on the web and a meshing with the planet gear arranged on the lifting table , internally toothed ring gear segment.

Auf Grund der gegenüber dem Hubtisch drehbaren Lagerung der Bundauflage braucht zum Wenden des Bun-des dieser nicht mehr vom Bundwagen abgehoben zu werden, so daß auch alle mit dem Abheben verbundenen Nachteile entfallen. Der mittig auf der Bundauflage liegende Bund wird bei angehobenem Hubtisch einfach mit der Bundauflage um deren Drehachse um 180° verschwenkt, wobei die Drehachse der Bundauflage selbstverständlich durch die Auflagenmitte hindurchgehen muß, um beim Verschwenken keine Versetzungen zu erhalten.Due to the rotatable mounting of the collar support relative to the lifting table, it no longer needs to be lifted off the coil carriage to turn the bu n-des, so that all the disadvantages associated with lifting are eliminated. When the lifting table is raised, the collar lying in the middle of the collar support is simply adjusted by 180 ° with the collar support around its axis of rotation pivots, the axis of rotation of the collar support must of course pass through the center of the support in order not to receive dislocations when pivoting.

Grundsätzlich ist die Schwenkbarkeit von Bundauflagen bekannt, doch dienen die bekannten, schwenkbaren Bundauflagen nur dazu, die einem Abwickelhaspel zuzuführenden Bunde mit Hilfe einer senkrecht zur Förderrichtung des Bundes angeordneten Schere beschneiden zu können, was einen Schwenkwinkel von 90° erfordert. Gemäß dem Stand der Technik soll durch das Verschwenken der Bundauflage um 90° die Achsrichtung der Blechbunde gegenüber einer Bearbeitungs- oder Transporteinrichtung ausgerichtet werden, was im Gegensatz zur Erfindung steht, weil die Bunde ja bereits ausgerichtet sind und diese Ausrichtung beibehalten werden soll.Basically, the pivotability of collar supports is known, but the known, pivotable collar supports only serve to be able to cut the bundles to be fed to a decoiler with the aid of scissors arranged perpendicular to the conveying direction of the collar, which requires a pivoting angle of 90 °. According to the prior art, the axial direction of the coil should be aligned with a processing or transport device by pivoting the collar support by 90 °, which is in contrast to the invention, because the coil is already aligned and this alignment is to be maintained.

Da zum Wenden der Bunde zur Erreichung eines vorgegebenen Abwickelsinns lediglich ein Verschwenken der im Hubtisch gelagerten Bundauflage um 180° notwendig ist, ist die konstruktive Ausgestaltung des Schwenkantriebes an sich-nicht beschränkt. Wegen der geringen Platzverhältnisse und der anzustrebenden Einfachheit des Antriebes sollten jedoch vergleichsweise kurze Stellwege ausreichen, um einen Schwenkwinkel von 1800 sicherzustellen. Dies wird in besonders günstiger Weise dadurch bewerkstelligt, daß die Bundauflage über den Steg eines Umlaufgetriebes angetrieben wird, so daß der Steg nur um einen vergleichsweise kleinen Winkel verschwenkt zu werden braucht, um eine Drehung des mit der Bundauflage drehfest verbundenen Zentralrades von 180° zu erreichen. Zum Antrieb des Steges kann daher in an sich bekannter Weise ein einfacher, am Hubtisch gelagerter Hydraulikzylinder verwendet werden.Since only a pivoting of the collar support mounted in the lifting table by 180 ° is necessary to turn the bundles in order to achieve a given unwinding direction, the structural design of the pivot drive is not limited per se. Because of the small space and the aspired simplicity of the drive, however, should be sufficient to a swivel angle of 180 0 ensure comparatively short travel ranges. This is accomplished in a particularly favorable manner in that the collar support is driven via the web of an epicyclic gear, so that the web only has to be pivoted by a comparatively small angle in order to achieve a rotation of the central wheel connected to the collar support in a rotationally fixed manner by 180 ° . A simple hydraulic cylinder mounted on the lifting table can therefore be used to drive the web in a manner known per se.

Der Schwenkwinkel des Steges und damit des Zentralrades kann dabei durch die Hublänge des Hydraulikzylinders bestimmt werden. Es ist aber auch ohne weiteres möglich, entsprechende Endschalter vorzusehen, die die Zylinderbeaufschlagung steuern. Beim Vorsehen von solchen Endschaltern braucht der Zylinderhub nicht auf das Übersetzungsverhältnis des Umlaufgetriebes abgestellt zu werden. Außerdem könnten auch Schwenkwinkel von 90° erreicht werden, um die Blechbunde, wie dies bekannt ist, gegenüber von Bearbeitungsanlagen, beispielsweise einer Schere, ausrichten zu können.The swivel angle of the web and thus of the Zen tralrades can be determined by the stroke length of the hydraulic cylinder. However, it is also readily possible to provide corresponding limit switches that control the application of cylinder. When such limit switches are provided, the cylinder stroke does not have to be adjusted to the gear ratio of the epicyclic gear. In addition, a swivel angle of 90 ° could also be achieved in order to be able to align the sheet coils, as is known, with respect to processing systems, for example scissors.

In der Zeichnung ist der Erfindungsgegenstand in einem Ausführungsbeispiel schematisch dargestellt. Es zeigen

  • Fig. 2 diesen Bundwagen im Schnitt nach der Linie II-II der Fig. 1.
In the drawing, the object of the invention is shown schematically in one embodiment. Show it
  • Fig. 1 shows a coil carriage according to the invention for conveying sheet metal coils in partial longitudinal section and
  • 2 shows this coil carriage in section along the line II-II of FIG. 1st

Der dargestellte Bundwagen 1 ist über Laufräder 2 auf Schienen 3 mittela eines nicht näher dargestellten Hydraulikmotors verfahrbar und besitzt einen Hubtisch 4, der mit Hilfe von Führungsstangen 5 vertikal verschiebbar im Bundwagen 1 gelagert.ist. Zum Heben und Senken dieses Hubtisches 4 diunt ein Hydraulikzylinder 6, der im Bundwagen 1 untergebracht ist.The coil carriage 1 shown can be moved via wheels 2 on rails 3 by means of a hydraulic motor (not shown in more detail) and has a lifting table 4 which is mounted in the coil carriage 1 so that it can be displaced vertically with the aid of guide rods 5. To raise and lower this lifting table 4 diunt a hydraulic cylinder 6, which is housed in the coil carriage 1.

Die Bundauflage 7 des Bundwagens 1 wird nicht im herkömmlichen Sinn vom Hubtisch 4 gebildet, sondern ist als-eigener Bauteil auf einem vertikalen, vom Hubtisch 4 getragenen Lagerzapfen 8 drehbar gelagert. Zum Verdrehen dieser Bundauflage 7 dient ein Umlaufgetriebe 9, dessen Zentralrad 10 koaxial zum Lagerzapfen 8 an der Unterseite der Bundauflage befestigt ist. Das mit dem Zentralrad kämmende Umlaufrad 11 wird von einem drehbar auf dem Lagerzapfen 8 gehaltenen Steg 12 getragen, der mit Hilfe von zwei diametral angreifenden, am Hubtisch 4 angeordneten Hydraulikzylindern 13 verschwenkt wird. Da bei einer Verschwenkung des Steges 12 das Umlaufrad 11 an einem fest mit dem Hubtisch 4 verbundenen, innenverzahnten Zahnkranzsegment 14 abgewälzt wird, wird über das Umlaufrad 11 auch das Zentralrad 10 und damit die Bundauflage 7 verdreht, wobei mit einem vergleichsweise, kleinen Schwenkwinkel des Steges 12 ein großer Verdrehwinkel für die Bundauflage 7 erreicht wird. Mit entsprechenden Anschlägen auf der Unterseite der Bundauflage 7 zusammenwirkende Endschalter 15 begrenzen den Verstellweg, so daß die für ein Wenden der Bunde notwendigen Schwenkwinkel von 180° sicher eingehalten werden können.The collar support 7 of the collar carriage 1 is not formed in the conventional sense by the lifting table 4, but is rotatably supported as a separate component on a vertical bearing journal 8 carried by the lifting table 4. An epicyclic gear 9 serves to rotate this collar support 7, the central wheel 10 of which is fastened coaxially to the bearing journal 8 on the underside of the collar support. The planet wheel 11 meshing with the central wheel is supported by a web 12 which is rotatably held on the journal 8 and which is pivoted with the aid of two diametrically acting hydraulic cylinders 13 arranged on the lifting table 4. Since, when the web 12 is pivoted, the planetary gear 11 is rolled on an internally toothed ring gear segment 14 which is fixedly connected to the lifting table 4, the central gear 10 and thus the collar support 7 is also rotated via the planetary gear 11, with a comparatively small pivoting angle of the web 12 a large angle of rotation for the collar support 7 is reached. Limit switches 15 which cooperate with corresponding stops on the underside of the collar support 7 limit the adjustment path, so that the pivoting angle of 180 ° necessary for turning the bundles can be reliably maintained.

Da bei mehreren hintereinandergeschalteten Bundwagen jeder Bundwagen jeden Bund um einen Förderschritt weiterfördert, braucht bei einer solchen Förderanlage nur ein Bundwagen mit einer verschwenkbaren Bundauflage versehen zu werden, obwohl selbstverständlich auch mehrere oder alle Bundwagen damit ausgerüstet sein können. Die zur Kupplung mit dem anschließenden Bundwagen vorgesehenen Hydraulikzylinder sind in der Zeichnung mit dem Bezugszeichen 16 versehen. Über die Einstellung des Abstandes zwischen zwei aufeinanderfolgenden Bundwagen kann die mittige Aufnahme der Blechbunde durch die Bundauflage sichergestellt werden.Since with several coil wagons connected in series, each coil wagon conveys each coil one step further, only one coil wagon needs to be provided with a swiveling coil support in such a conveyor system, although of course several or all coil wagons can also be equipped with it. The hydraulic cylinders provided for coupling with the adjoining coil carriage are provided with the reference number 16 in the drawing. By adjusting the distance between two consecutive coil trolleys, the central support of the sheet metal coils can be ensured by the coil support.
