Description

Die Erfindung betrifft eine Einrichtung zum Umsetzen von Blechteilen in einer Pressenanlage mit den weiteren Mitteln gemäß dem Oberbegriff des Anspruchs 1. In Pressenanlagen werden infolge immer größer werdender zu verarbeitender Blechteile bzw. höherer Losgrößen die Umsetzgeschwindigkeiten der Blechteile von der Einlege- bzw. Orientierstufe durch die Pressenanlage bis zur Werkstückabgabe immer größer. Dies hat in der Vergangenheit zu masseärmeren Umsetzeinrichtungen geführt. Darüberhinaus entsteht beim Drehen des Blechteils als Notwendigkeit des Herausnehmens aus den Werkzeug und/oder mit Bezug auf die Lage des Blechteils im nachfolgenden Werkzeug ein Mittenfehler des Blechteils.The invention relates to a device for converting sheet metal parts in a press system with the further means according to the preamble of claim 1. In press systems, the conversion speeds of the sheet metal parts from the insertion or orientation stage through the are increasing due to ever increasing sheet metal parts to be processed or larger batch sizes Press system getting bigger and bigger until the workpiece is released. In the past, this has led to low-mass transfer devices. In addition, when the sheet metal part is rotated, a center error of the sheet metal part arises as a necessity for removal from the tool and / or with reference to the position of the sheet metal part in the subsequent tool.

In der -A-DE 41 04 810 ist eine Einrichtung zum Umsetzen von Blechteilen in einer Pressenanlage beschrieben, bei der die Blechteile während der Bewegung von Bearbeitungsstufe zu einer Zwischenablage und weiter aus dieser in die nachfolgende Bearbeitungsstufe im Hinblick auf die Lage der Blechteile in den Werkzeugen gedreht werden. Hierfür weist die Einrichtung saugerbestückte Quertraversen auf. Die Quertraversen sind endseitig in Drehlagern schienengeführter Laufwagen befestigt. Die Laufwagen sind in Verfahrbewegungen über ein Transportgestänge pressegesteuert; die Schienen sind entsprechend hebe- und senkbar.In -A-DE 41 04 810 a device for converting sheet metal parts in a press system is described, in which the sheet metal parts during the movement from the processing stage to an intermediate storage and further into the subsequent processing stage with regard to the position of the sheet metal parts in the Tools are rotated. For this purpose, the device has suction cross members. The crossbeams are fixed at the end in pivot bearings on rail-guided carriages. The carriages are press-controlled in travel movements via a transport linkage; the rails can be raised and lowered accordingly.

Desweiteren ist in der US-A-4,625,540 eine Umsetzeinrichtung beschrieben mit einem in heb- und senkbaren Laufschienen geführten und horizontal bewegbaren Rahmengestell. An diesem sind Quertraversen über Verstellmittel zusätzlich in einer solchen Weise bewegbar, daß diese in Zeiten des Stößelniedergangs ohne Blechteil in einen Bereich zwischen Stößel bzw. Werkzeug zum kurzzeitigen Halten geführt werden.Furthermore, a transfer device is described in US Pat. No. 4,625,540 with a frame frame that is guided and can be moved horizontally in lifting and lowering rails. At this crossbars are over Adjustment means can also be moved in such a way that they are guided without a sheet metal part into a region between the plunger or tool for a brief stop in times of the tappet decline.

In der DE-A-39 31 081 ist eine Zwischenablage beschrieben in einer Ablagestation mischen zwei Bearbeitungsstufen einer Presse. Die Zwischenablage weist Schablonen auf zum Abstützen der Blechteile, die durch Stell- und Bewegungs-Umlenkmittel in Höhe, Abstand und Schräglage für ein anderes Blechteil bzw. auf eine nachfolgende Bearbeitungsstufe einstellbar sind. Der durch Schwenken des Blechteils bewirkte Fehler ist mit den Verstellmitteln für die horizontale und die vertikale Bewegung der Schablonen anzugleichen.DE-A-39 31 081 describes a clipboard in a storage station mixing two processing stages of a press. The clipboard has templates for supporting the sheet metal parts, which can be adjusted in height, distance and inclined position for another sheet metal part or for a subsequent processing step by means of adjusting and moving deflection means. The error caused by swiveling the sheet metal part must be corrected with the adjustment means for the horizontal and vertical movement of the templates.

Aus der GB-A-2 243 134 ist eine Einrichtung zum Umsetzen von Blechteilen in einer Pressenanlage bekannt, bei welcher Blechteile haltende und diese bewegende Haltemittel als Quertraversen ausgebildet und endseitig an Laufwagen befestigt sind.
Die Quertraversen sind durch Antriebe auf Schienen horizontal verfahrbar und mit diesen heb- und senkbar. Der Befestigungspunkt der Quertraversen an den Laufwagen ist zudem in Richtung der Verfahrbewegung der Laufwagen durch einen weiteren Antrieb verstellbar. Mit der hier aufgezeigten Einrichtung werden Blechteile während der Umsetzbewegung nicht in einer zusätzlichen Verschiebebewegung relativ zum Laufwagen bewegt.From GB-A-2 243 134 a device for converting sheet metal parts in a press system is known, in which sheet metal parts holding and moving these holding means are designed as cross members and are attached at the end to carriages.
The cross beams can be moved horizontally by drives on rails and can be raised and lowered with them. The point of attachment of the crossbeams to the carriage can also be adjusted in the direction of the movement of the carriage by another drive. With the device shown here, sheet metal parts are not moved in an additional displacement movement relative to the carriage during the transfer movement.

Gegenüber diesem Stand der Technik ist es Aufgabe der Erfindung, die Haltemittel an dem/den Laufwagen relativ zu diesem/diesen verschiebbar anzuordnen, um so einerseits den Umsetzweg des einzelnen Laufwagens zu verringern und um andererseits die ggf. von Laufwagen zu Laufwagen unterschiedlichen, als Folge des Drehens der Blechteile erforderlichen Korrekturbewegungen auszugleichen.Compared to this prior art, it is an object of the invention to arrange the holding means on the carriage (s) so as to be displaceable relative to the carriage (s), in order to reduce the movement distance of the individual carriage on the one hand and, on the other hand, to change the carriage from carriage to carriage as a result of the turning of the sheet metal parts to compensate for the necessary correction movements.

Diese Aufgabe ist gelöst durch die im Anspruch 1 angegebenen Merkmale. Anspruch 2 stellt eine vorteilhafte Ausgestaltung der Erfindung dar. Durch die Addition der Verstellbewegungen von zwei Bewegungsantrieben der Quertraverse sind einerseits kurze Bewegungen des Transportgestänges bei gleicher Umsetzbewegung unter Erhöhung der Anzahl an Umsetzbewegungen, andererseits sind bei gleicher Anzahl an Umsetzbewegungen größere Umsetzbewegslängen erreichbar.This object is achieved by the features specified in claim 1. Claim 2 represents an advantageous embodiment of the invention. By adding the adjustment movements of two movement drives of the cross-member, on the one hand short movements of the transport linkage with the same conversion movement while increasing the number of conversion movements, and on the other hand larger conversion movement lengths can be achieved with the same number of conversion movements.

Ein weiterer wesentlicher Vorteil der Erfindung ist dadurch gegehen, daß bei Nutzung der Zusatzbewegungsmittel Korrekturbewegungen, z.B. solche, die durch Drehung der Quertraverse erforderlich werden, ausgeglichen werden können.Another important advantage of the invention is that corrective movements, e.g. those that are required by turning the crossbar can be compensated.

Anhand eines in der Zeichnung dargestellten Ausführungsbeispiels soll im folgenden die Erfindung näher erläutert werden.Based on an embodiment shown in the drawing, the invention will be explained in more detail below.

In Fig. 1 ist eine Laufschiene 1 gezeigt, die in einer Presse, Transferpresse o.dgl. Pressenanlage in Richtung des Doppelpfeils 21 heb- und senkbar ist. Die Laufschiene 1 erstreckt sich in Richtung der Umsetzbewegung 20 von Blechteilen 11 durch die Presse. In der Regel sind zwei Laufschienen der Art vorhanden, von denen sich eine vor, die zweite hinter Stößel und Werkzeug erstrecken und auf denen jeweils Laufwagen 3 in der Anzahl erforderlicher Quertraversen 10 bewegbar gelagert und vom Pressenantrieb, mechanisch oder elektrisch, angetrieben werden.In Fig. 1, a running rail 1 is shown, or the like in a press, transfer press. Press system in the direction of the double arrow 21 can be raised and lowered. The running rail 1 extends in the direction of the transfer movement 20 of sheet metal parts 11 through the press. As a rule, there are two rails of the type, one of which extends in front, the second behind the ram and tool, and on each of which carriages 3 are movably mounted in the number of required cross members 10 and are driven mechanically or electrically by the press drive.

Die Laufschiene 1 ist mit Laufflächen 2 versehen, auf denen Laufrollen 6 eines insgesamt mit 3 positionierten Laufwagens abrollen. Der gezeigte Laufwagen 3 ist in seinem Grundaufbau zweigeteilt mit einem Wagenteil 4 und einem Wagenteil 5. An den Wagenteil 4 ist, wie es Fig. 2 erkennen läßt, über den Anguß 8 ein vom Pressenantrieb beaufschlagtes Transportgestänge 7 befestigt, über das der Laufwagen 3 auf der Laufschiene 1 horizontal verfahrbar ist. Der Wagenteil 5 weist einen Drehpunkt 12 auf, der als Befestigungspunkt für eine hier drehbar gelagerte Quertraverse 10 dient. Diese ist mit Saugern o.dgl. Mittel 13 versehen zum Halten von Blechteilen 11 beim Entnehmen aus der Entstapelstation oder dem Werkzeug und zum Umsetzen in die folgende Station bis zum Ablegen in dieser. Zwischen dem Wagenteil 4 und dem Wagenteil 5 ist ein Linearmotor, Druckzylinder o.dgl. Verstellmittel 9 angebracht für eine Relativbewegung zwischen den Wagenteilen 4 und 5. Somit ist der Wagenteil 5 an den Wagenteil 4 angeschlossen und bewegt sich wie dieser infolge des Pressenantriebs. Darüberhinaus ist eine Zusatzbewegung über die Länge der Verstellbarkeit des Verstellmittels 9 möglich. Befindet sich die Spindel 23 bzw. der Kolben des Verstellmittels 9 während der Umsetzbewegung des Laufwagens 3 in zumindest teilweise ausgefahrener Stellung, ist die Reduzierung der Gesamtbewegung des Laufwagens 3 bzw. des Wagenteils 4 bei Beaufschlagung des Verstellmittels 9 möglich. Die Drehverstellung der Quertraverse 10 erfolgt hier über einen Drehmotor 14, der am Wagenteil 5 angeflanscht ist. Quertraverse 10, Drehmotor 14 und somit der Befestigungspunkt 12 sind in Schienen 24 geführt und vermittels Verstellmittel 25 heb- und senkbar.The running rail 1 is provided with running surfaces 2, on which running rollers 6 of a carriage positioned in total with 3 roll. The carriage 3 shown is divided into two parts in its basic structure with a carriage part 4 and a carriage part 5. On the carriage part 4, as can be seen in FIG the running rail 1 can be moved horizontally. The carriage part 5 has a fulcrum 12, which serves as an attachment point for a cross-member 10 rotatably mounted here. This is with suction cups or the like. Means 13 are provided for holding sheet metal parts 11 when removing them from the unstacking station or the tool and for transferring them to the following station until they are placed in the latter. Between the carriage part 4 and the carriage part 5 is a linear motor, pressure cylinder or the like. Adjustment means 9 attached for a relative movement between the carriage parts 4 and 5. Thus the carriage part 5 is connected to the carriage part 4 and moves like this as a result of the press drive. In addition, an additional movement over the length of the adjustability of the adjusting means 9 is possible. If the spindle 23 or the piston of the adjusting means 9 is in the at least partially extended position during the moving movement of the carriage 3, it is possible to reduce the total movement of the carriage 3 or the carriage part 4 when the adjusting means 9 is acted upon. The crossbar 10 is rotated here by means of a rotary motor 14 which is flanged to the carriage part 5 is. Crossbar 10, rotary motor 14 and thus the attachment point 12 are guided in rails 24 and can be raised and lowered by means of adjusting means 25.

In den weiteren Figuren sind gleiche Teile gleich beziffert. Fig. 2 läßt neben der Mehrteiligkeit des Laufwagens 3 die Beaufschlagung des Wagenteils 4 durch das Transportgestänge 7 und die Anordnung des Drehmotors 14 erkennen. Die Quertraverse 10 ist abgebrochen dargestellt. Der anderseitige Endteil dieser ist an einem Laufwagen drehbar gelagert, der gleichermaßen ausgebildet und in einer zweiten Laufschiene bewegbar ist. Die Schnittdarstellung der Fig. 3 läßt die Einzelteile des Laufwagens, hier des Wagenteils 5 erkennen.In the other figures, the same parts are numbered the same. Fig. 2 shows in addition to the multi-part of the carriage 3, the action of the carriage part 4 by the transport linkage 7 and the arrangement of the rotary motor 14.
