Automated vacuum gripper and method for securely gripping components

Abstract

The invention relates to a method for conveying components and to an automated vacuum gripper () for components (), in particular sheet metal parts, comprising a plurality of suction elements (), which are arranged at a preferably movable support part (), a first vacuum generator () for forming a first vacuum circuit (), a second vacuum generator () for forming a second vacuum circuit (), at least one switching element connected to a system controller () for automated switching of the first vacuum circuit () to the second vacuum circuit (), at least one compressed air supply () connected to at least the first and the second vacuum generators (), at least one sensor device (), wherein the first vacuum generator () is associated with a first predeterminable group () of suction elements (), and the second vacuum generator () is connected to a vacuum tank () for forming a second vacuum circuit (), which may be activated in case of emergency and is redundant to the first vacuum circuit (), and wherein at least one first sensor device is () is formed for monitoring the vacuum at least at the first vacuum circuit (), and at least one second sensor device () has an optical sensor for detecting a relative movement of the component () during a conveying operation.
