Abstract (en)

A transmitter (8) connected to the sensor, reports the number of turns detected, to a remote receiver (5). Preferred features: The transmitter employs IR or radio signals. The receiver is connected to the machine controller or forms a component of it. The receiver tests the value of the number of turns. The sensor includes a row of photocells (6) to measure light reflected from the guide, in the region wrapped by turns. Each cell measures reflected light in a discrete region of the guide (1, 2). The sensor is formed by a light beam moved along the guide and the wrapping of threads. The sensor may be constructed as a measurement gun with handle and sighting device, which projects a marking to indicate the measurement region on the thread guide. The gun has a fork which can be slid along the group of threads on the guide, leaving clearance, and having the measurement beam across its open end. A press-button (16) initiates transmission from it to the receiver.

Abstract (de)

Die Einrichtung enthält einen elektro-optischen Sensor (6') zur Messung der Anzahl der Fadenwindungen und einen mit dem Sensor (6') verbundenen Sender (8) für die drahtlose Übertragung der vom Sensor (6') ermittelten Anzahl der Fadenumschlingungen an einen räumlich entfernten Empfänger (5). Im Empfänger (5), der mit der Maschinensteuerung verbunden ist oder Bestandteil von dieser bildet, erfolgt eine Überprüfung des empfangenen Werts der Anzahl der Fadenwindungen. Die vom Sender (8) übertragene Anzahl der Fadenumschlingungen wird mit einem Sollwert verglichen und das Ergebnis dieses Vergleichs wird in einem Qualitätsprotokoll festgehalten. <IMAGE>
