Abstract:
A glass machine system that includes:a glassware manufacturing machine for manufacturing articles of glassware and transferring such articles to a linear conveyor, at least one linear conveyor for receiving and transporting such articles from the machine, and a speed sensor for monitoring linear speed of the conveyor comprising: a magnetic energy source, a magnetic energy sensor, bracketry mounting said energy source and said energy sensor adjacent to said conveyor, said conveyor affecting magnetic energy coupling between said energy source and said energy sensor as said conveyor passes adjacent to said speed sensor, and circuitry responsive to signals from said energy sensor for determining speed of said conveyor, said conveyor having teeth along an undersurface thereof for engaging a pulley to drive said conveyor, passage of said teeth affecting magnetic coupling between said energy source and said energy sensor, said bracketry including first bracketry for mounting in fixed position adjacent to said conveyor, and second bracketry movable mounted on said first bracketry for maintaining a fixed spacing between said energy sensor and said conveyor teeth, said second bracketry including at least one roller in rolling engagement with an upper surface of said conveyor, said magnetic energy sensor being suspended beneath said conveyor by said second bracketry.
