Title: DRIVE MECHANISM WITH A SENSOR DEVICE FOR DRIVING A HEALD FRAME OF A WEAVING MACHINE
Abstract:
A drive mechanism for driving a heald frame (1) of a weaving machine, the drive mechanism (2) comprising a sensor device(20), wherein the sensor device (20) comprises at least three members comprising both a target set with one or more targets (21, 22) and a detector set with one or more detectors (23), wherein one of the detector set and the target set is arranged at the swivel lever (6) and the other one is arranged stationary on the weaving machine, wherein targets (21, 22) of the target set and/or detectors (23) of the detector set have different characteristics for generating a first signal (24) when approaching the measuring position from the upper position or when departing from the measuring position towards the upper position and for generating a second signal (25) when approaching the measuring position from the lower position or when departing from the measuring position towards the lower position, wherein the second signal (25) differs from the first signal (24). A method for detecting the presence of a swivel lever (6) of a drive mechanism (2) for driving a heald frame (1) of a weaving machine in a measuring position.
