Abstract
An apparatus (50) for detecting lateral deviation of a band saw blade (36) from the desired line of cut which includes an angularly displaceable element (54) slidably engaging the saw blade (36) for pivotal movement therewith. A relatively rigid mounting assembly (52,64) mounts the angularly displaceable element (54) for rotation while resisting lateral displacement. Lateral blade deviation is proportionately determined when angular displacement is sensed by a sensor (55) as the blade (36) contacts the displaceable element (54) rotating it about an axis (53) through the desired plane of the blade (36). The angular deflection sensing assembly 50 also may be incorporated into a guide arm (32).
Claims16
An apparatus for the detection of lateral deviation of a band saw blade from a specified line of cut of a band saw machine as said band saw blade cuts through a workpiece, said apparatus including two guide assemblies located on opposite sides of and defining a cutting stretch, and detecting means mounted to said band saw machine proximate one of said guide assemblies for detecting said lateral deviation, wherein the improvement comprises:
- said detecting means including an angularly displaceable element, mounting means mounting said angularly displaceable element for rotation about a vertical axis through said specified line of cut in response to angular displacement of said blade, and sensing means mounted to and sensing rotational displacement of said angularly displaceable element to thereby detect lateral deviation of said blade in said cutting stretch.
