Thread breakage detection systems and methods
First Claim
1. A system comprising:
- a textile sewing apparatus having at least one yarn guide plate defining a plurality of holes through which thread may pass; and
a thread breakage detection apparatus coupled to the textile sewing apparatus, the thread breakage detection apparatus comprising;
a light source operable to generate a light beam;
an emitter in communication with the light source, the emitter operable to emit the light beam, the emitter comprising an emitter lens; and
a receiver in communication with the emitter, the receiver operable to receive the light beam emitted from the emitter and to communicate the light beam to a sensor, the receiver comprising a receiving lens, wherein in order to minimize false positives;
the light beam is proximate to the yarn guide plate, anda distance between the light beam and a thread disposed in one of the plurality of holes defined by the yarn guide plate comprises approximately 10 millimeters.

Abstract
A thread breakage detection apparatus comprises a light source operable to generate a light beam, an emitter in communication with the light source, the emitter operable to emit the light beam, and a receiver in communication with and disposed in facing opposition to the emitter, the receiver operable to receive the light beam emitted from the emitter and to communicate the light beam to a sensor. The emitter comprises an emitter lens and a first fiber optic cable comprising proximate and distal ends. The proximate end of the first cable in communication with the light source and the distal end of the first cable in communication with the emitter lens. The receiver comprises a receiving lens and a second fiber optic cable comprising proximate and distal ends, the proximate end of the second cable in communication with the receiving lens and the distal end of the second cable in communication with the sensor.
