Abstract:
1. A device for detecting the faulty position of and separating fasteners, more particularly blind rivets in a continuously operating conveyor apparatus by means of which the fasteners are supplied to an automated joining machine, wherein each fastener is followed by a spacer, the device comprising: at least three contactless detectors configured to determine the position of the fasteners, where the detectors are inductively and/or capacitively operating ring initiators; a switching gate configured to remove the fasteners in a faulty position as well as the spacers from the conveyor apparatus so that only fastener elements in the correct position are delivered individually to the automated joining machine, and wherein a response threshold of the ring initiators for the passage of a fastener element or a space can be adjusted in order to determine different sections of the fastener and/or to differentiate between the spacers and the fasteners.
