Abstract

Eine Transfereinrichtung 1 weist wenigstens ein Transfermittel 12, 14 auf, das mit mehreren voneinander unabhängigen Antrieben 17, 18 in Richtung wenigstens einer Achse C, O angetrieben wird. Um bei Ausfall eines Antriebs 17, 18 ein unmittelbares Stehenbleiben von Teilen des Transfermittels zu verhindern, sind die Antriebe 17, 18 über eine Kupplungseinrichtung 37 miteinander gekuppelt. Diese weist einen Arbeitsbereich geringer Drehmomentübertragung auf, der normalerweise eingenommen und nur dann verlassen wird, wenn einer der Antriebe 17, 18 keine ausreichende Antriebsleistung mehr liefert.

Figure 00000001
A transfer device 1 has at least one transfer means 12, 14 which is driven in the direction of at least one axis C, O by a plurality of mutually independent drives 17, 18. In order to prevent parts of the transfer means from stopping immediately if a drive 17, 18 fails, the drives 17, 18 are coupled to one another via a coupling device 37. This has a working area of low torque transmission, which is normally taken up and only left when one of the drives 17, 18 no longer delivers sufficient drive power.
