ABSTRACT:
A wire prebreak/break sensor is disclosed for use in a low cost verbal annunciator system for use in monitoring a wire fabrication process. Wire exiting a drawing machine is accumulated and has its tension controlled by a dancer arm. According to the present invention, a wire accumulator having a plurality of channels is used as a wire prebreak/break sensor. The accumulator comprises a plurality of rods having sheaves on a end of each supported on a support structure to which each rod is pivoted on an axis. A plurality of position sensors are responsive to the positions of the various rods and provide a position signal having a magnitude indicative thereof. An operator input device is responsive to operator initiated input action for providing input signals indicative of wire gauge. A signal processor is responsive to the position signals and to the operator input signals and retrieves a pair of boundary signals in response to the magnitude of the gauge size input signals. The magnitudes of the boundary signals will vary depending on the gauge selected. The signal processor compares the magnitudes of the position signals to the boundary signals and provides an alarm signal whenever one of the position signal magnitudes is greater or less than the magnitudes of both of the boundary signals. The signal indicating a broken wire is provided to the verbal annunciator so that immediate corrective action may be taken by maintenance personnel.
