Abstract
Bei einem Stanzautomaten zum Ausstanzen von Dosendeckeln aus Blechtafeln (5) mit einer Zuführungseinrichtung, die Blech tafeln (5) in das Werkzeug schiebt und schrittweise zur Durchführung der zeitlich nacheinander ablaufenden Stanz vorgänge transportiert, bedarf eine Formatänderung der Blechtafeln (5) keiner mechanischen Umrüstung der Zufüh rungseinrichtung und wird der Transport der Blechtafeln (5) im Bereich des Werkzeuges ununterbrochen in allen Beschleunigungs- und Abbremsvorgängen kontrolliert durch ein in Zuführungsrichtung vor dem Werkzeug (2) angeordnetes, durch einen numerischen Antrieb (15) antreibbares ersten Walzenpaar (9), das mit einer oberen Walze (13) an der Oberseite und mit einer unteren Walze (11) an der Unterseite der Blechtafel (5) anliegt, ein entsprechendes zweites Walzenpaar (17) auf der gegenüberlie genden Seite (16) des Werkzeugs (2) und durch eine Steuerung, durch die das erste Walzenpaar (9) die Blechtafel (5) aus einer Warteposition kontinuierlich in das Werkzeug (2) zieht und anschließend sofort auf einen schrittweisen Antrieb umgeschaltet wird, durch die der schrittweise Antrieb nach Zurücklegen eines vorbestimmten Transportweges in dem Werkzeug (2) von dem ersten Walzenpaar (9) auf das zweite Walzenpaar (17) um-geschaltet wird und durch die das zweite Walzenpaar (17) nach dem schrittweisen Antrieb auf eine kontinuierliche Ausschubbewegung umgeschaltet wird, wobei das Einziehen einer nachfolgenden Blechtafel (5) durch das erste Walzenpaar (9) ohne Zwischenraum bis an die vorhergehende Blechtafel (5) erfolgt, während das zweite Walzenpaar (17) noch schrittweise vorschiebt und während des schrittweisen Vorschubs durch das erste Walzenpaar (9) das zweite Walzenpaar (17) die Ausschubbewegung vornimmt. With an automatic punching machine for punching out can lids Metal sheets (5) with a feed device, the sheet metal plates (5) into the tool and step by step Execution of the stamping that takes place in succession processes transported, the format needs to be changed Metal sheets (5) no mechanical conversion of the feed approximately and the transport of the metal sheets (5) in Area of the tool continuously in all acceleration and braking processes controlled by a feed direction arranged in front of the tool (2) by a numerical Drive (15) drivable first pair of rollers (9) with a upper roller (13) on the top and with a lower roller (11) on the underside of the sheet (5) corresponding second pair of rollers (17) on the opposite opposite side (16) of the tool (2) and by a controller, through which the first pair of rollers (9) the sheet (5) from a Waiting position continuously pulls into the tool (2) and then immediately switched to a step-by-step drive through which the gradual drive after driving a predetermined transport path in the tool (2) from the first Roller pair (9) is switched to the second pair of rollers (17) and through which the second pair of rollers (17) after the gradual Drive switched to a continuous extension movement , whereby the drawing in of a subsequent sheet of metal (5) through the first pair of rollers (9) with no space up to previous sheet (5) takes place while the second Roller pair (17) still feeds gradually and during the gradual feed through the first pair of rollers (9) the second Roller pair (17) makes the extension movement.
