Abstract
A band saw blade sensor and control system to sense and control saw blade deviation of a continuous, flexible metal saw blade driven around a pair of pulleys. A pair of spaced proximity inductive sensors is positioned adjacent to a side of the saw blade in order to detect blade deviation during operation. A controller mechanism receives input from each of the pair of inductive sensors in order to control and adjust band tension on the blade, and in order to control and adjust blade force on a work piece.
Claims10
A band saw blade sensor and control system to sense and control saw blade deviation of a continuous, flexible metal saw blade driven around at least a pair of pulleys, which system comprises:
- a pair of spaced proximity inductive sensors adjacent to a side of said saw blade to detect blade deviation;
- and
- a controller mechanism to receive input from each of said pair of sensors, to control and adjust band tension on said blade, and to control and adjust blade force on a work piece.
A process to sense and control blade deviation of a continuous, flexible metal saw blade driven around a pair of pulleys, which process comprises:
- sensing position of said continuous, flexible metal saw blade with a pair of spaced proximity inductive sensors adjacent to a side of said blade;
- delivering said position information from said sensors to a controller;
- varying the set point of blade force on a work piece;
- and
- varying the band tension of said blade.
