Abstract

Bei einer Pressenanlage 1 sind in den Pressenstationen 2, 3 Schiebetische 9, 9' vorgesehen, die Werkzeuge 8, 8' tragen. An den Schiebetischen 9, 9' oder an den Werkzeugen 8, 8' sind Halterungen 22, 22' vorgesehen. Diese dienen der Aufnahme von Haltern 49, 49', die an der zwischen den Pressenstationen 2, 3 angeordneten Zwischenablagestation 4 angeordnet sind. Die Halter 49, 49' tragen Schablonen 43 zur Zwischenablage von Werkstücken. Außerdem weisen sie Aufnahmemittel 46, 48; 46', 48' auf, mit denen sie werkstückspezifische Teile des Transfersystems insbesondere Saugerrahmen 51, 51' aufnehmen können. Beim Werkzeugwechsel wird die Zwischenablagestation 4 so betätigt, dass sie mit ihren Haltern 49, 49' die Saugerrahmen 51, 51' aufnimmt, wonach die Halter 49, 49' an den Halterungen 22, 22' abgesetzt werden.

Figure 00000001
In a press system 1, sliding tables 9, 9 'are provided in the press stations 2, 3, which carry tools 8, 8'. Brackets 22, 22 'are provided on the sliding tables 9, 9' or on the tools 8, 8 '. These serve to accommodate holders 49, 49 ', which are arranged on the intermediate storage station 4 arranged between the press stations 2, 3. The holders 49, 49 'carry templates 43 for the intermediate storage of workpieces. In addition, they have receiving means 46, 48; 46 ', 48' with which they can accommodate workpiece-specific parts of the transfer system, in particular suction frames 51, 51 '. When changing tools, the intermediate storage station 4 is actuated so that it holds the suction frames 51, 51 'with its holders 49, 49', after which the holders 49, 49 'are placed on the holders 22, 22'.
