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.
Claims12
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 proximity inductive sensors spaced apart from each other, each of said sensors adjacent to a side of said saw blade to detect blade deviation;
- and
- a controller mechanism to receive input regarding said blade deviation from each of said pair of sensors, to control and adjust band tension on said blade in response to said blade deviation, and to control and adjust blade force on a work piece in response to said blade deviation.
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 proximity inductive sensors spaced apart from each other, each of said sensors adjacent to a side of said blade to detect blade deviation;
- delivering said position information and blade deviation from said sensors to a controller;
- varying the set point of blade force on a work piece in response to said blade deviation;
- and
- varying the band tension of said blade in response to said blade deviation.
A process to sense and control blade deviation of a continuous, flexible metal saw blade driven around a pair of pulleys, which process comprises:
- entering cut properties of a cut to be performed on material into a controller mechanism;
- comparing data from a pair of proximity inductive sensors, each of said sensors adjacent to a side of said blade in communication with said controller to determine the position of said blade and to determine if blade deviation has occurred;
- and
- varying the set point of blade force on a work piece in response to blade deviation or varying the band tension of said blade in response to said blade deviation.
