Description

Die Erfindung betrifft eine Presse, Mehrstufenpresse od. dgl. Umformmaschine gattungsbildender Art.The invention relates to a press, multi-stage press or the like. Forming machine of a generic type.

Die Endbereiche einer Presse sind dem Einlegen von Platinen und der Entnahme dieser nach der Formgebung zuzuordnen. Hierbei kann der Antrieb der Transportschienen für die Umsetzbewegung dem Entnahmebereich der Presse zugeordnet sein. Die Entnahme kann hierbei über ein Transportband erfolgen. Das Einlegen erfolgt über einen Platinenlader, der von seiner Bedeutung her, Vereinzeln von Platinen, Reinigen und ggf. Richten dieser, Orientieren und Einlegen der Platinen in eine erste Station der Presse, auch im Einlegebereich der Presse platz- bzw. raumaufwendig ist. Bei bisherigen Pressen mit Transportschienen für das Umsetzen der Werkstücke reichen die Endbereiche der Transportschienen entsprechend dem Umsetzhub bis in den Bereich des Platinenladers. Durch die aufeinander zu geführte Bewegung zum Erfassen der Werkstücke und die Umsetzbewegung erfolgt eine wesentliche Einengung für den Platinenlader.The end areas of a press are assigned to the insertion of blanks and the removal of these after shaping. The drive of the transport rails for the transfer movement can be assigned to the removal area of the press. The removal can take place on a conveyor belt. Loading takes place via a blank loader, which is important in terms of size, separating blanks, cleaning and, if necessary, straightening them, orienting and inserting the blanks into a first station of the press, even in the insertion area of the press. In previous presses with transport rails for transferring the workpieces, the end regions of the transport rails extend into the area of the blank loader in accordance with the transfer stroke. The movement towards each other for gripping the workpieces and the transfer movement result in a significant restriction for the board loader.

Bis in den Bereich des Platinenladers und somit über den Bereich der Einleitung der Hebe- / Senkbewegung und der Öffnen- / Schließenbewegung hinausgeführte Transportschienen zeigen die Dokumente DE 28 16 928 C2, DE 33 29 900 C2 und EP 0 202 882 A2. Die hier gezeigten Pressen weisen insgesamt Lösungen für die Führung der Transportschienen auf, bei denen die durch die Länge der Umsetzbewegung bedingte Länge der Laufschienen in den bewegten Teil der Führung, also in die Transportschiene, eingerechnet ist. Einerseits müssen die Transportschienen um dieses Maß der Bewegung länger ausgeführt sein, andererseits kommt es zu den angesprochenen räumlichen Einschränkungen für den Platinenlader.The documents DE 28 16 928 C2, DE 33 29 900 C2 and EP 0 202 882 A2 show transport rails which extend into the area of the board loader and thus beyond the area for initiating the lifting / lowering movement and the opening / closing movement. The presses shown here have overall solutions for guiding the transport rails, in which the length of the running rails due to the length of the transfer movement is included in the moving part of the guide, that is to say in the transport rail. On the one hand, the transport rails must be made longer by this amount of movement, on the other hand, there are spatial restrictions for the board loader.

Demgegenüber ist es eine Aufgabe der Erfindung, eine Lösung für die genannten Probleme zu finden, bei der die Transportschienen für den Platinenlader keine Behinderung darstellen. Es können unterschiedlich aufgebaute und von daher dimensionierte Platinenlader zum Einsatz kommen.In contrast, it is an object of the invention to find a solution to the problems mentioned, in which the transport rails for the board loader are not a hindrance. Board loaders of different designs and therefore dimensioned can be used.

Diese Aufgabe ist gelöst bei einer Presse gattungsbildender Art durch die den Anspruch 1 kennzeichnenden Merkmale.This object is achieved in a press of a generic type by the features characterizing claim 1.

Die Merkmale der weiteren Ansprüche stellen bevorzugte Ausgestaltungen der Erfindung dar.The features of the further claims represent preferred embodiments of the invention.

Besondere Vorteile ergeben sich daraus, daß die eigentlichen Führungsschienen bzw. Führungsflächen in Umsetzeinrichtung nicht mitbewegt werden.Particular advantages result from the fact that the actual guide rails or guide surfaces are not moved in the transfer device.

Anhand eines Ausführungsbeispiels in der Zeichnung soll im folgenden die Erfindung näher erläutert werden.The invention will be explained in more detail below using an exemplary embodiment in the drawing.
