Patent ID: 10466035

Abstract:
An arrangement for automatically contactlessly detecting elongate objects (W), such as cables, wires or profiles, has a quasi-coaxially arranged group of a first optical measuring system (D) for determining the external diameter and a second optical measuring system (C) for determining the color using a different measurement principle. The functional and local separation of the two measuring systems (C, D) is achieved by using different wavelength ranges and by a long-pass filter (C3). A third, virtual measuring system (P) may be provided for the purpose of determining the cable location and is used to weight measured values of the color measurement and measured values of an optional eddy current sensor. The optical measuring systems (D, C, P) for determining the diameter, the color and the position have a common optical disc-shaped measuring volume (DCPv) which is preferably arranged centrally in the guide device (4a, 4b) for the elongate object (W).
