Device and method for detecting double parts

Abstract

The present invention relates to a device and a method for detecting double parts, and especially relates to an assembly of an additional photo receiver in addition to the known laser sensors for detecting double parts during transport and during the loading of machine, which are situated opposite each other. The additional photo receiver receives the laser beam from a laser sensor located opposite, exactly when there is no material in the measuring gap and the two laser sensors are precisely aligned. This arrangement makes it possible to improve the measuring process and the analysis of the measurement, and thereby increases process reliability during the monitoring of transport and the loading of machines.

Description

technical field

[0001] The invention relates to a method for detecting duplex parts (Doppelteil) during transport and during feeding of a machine by means of two laser sensors arranged opposite each other, the laser sensors respectively having a laser source and a detector, the parts being processed by the laser travel between source and detector, wherein the distance between the respective laser sensor and the surface of the component facing the laser sensor is measured, and the distance between the laser sensors from one another and the distance measured by the two laser sensors The difference between the sums to find the thickness of the part. Furthermore, the invention relates to a device for detecting multiple parts during transport and when feeding a machine, with two laser sensor units arranged opposite each other and with which the laser sensor units are connected or can be connected. A connected electronic control unit, the laser sensor units are arranged at a distan...
