SAW GUIDE PRESSURE FEED SPEED CONTROL SYSTEMS AND METHODS

摘要

A sawmill feedspeed control system having a force sensor operatively coupled to a sawguide of a sawblade, the output of the force sensor being processed and supplied to a motion controller and driver for reducing or increasing feed velocity of a workpiece so as to prevent overfeed or underfeed, while minimizing deviations of the blade from a straight cut and maximizing production throughput.

主权项

1. An apparatus for detection of a deviation of a saw cut from a true cut line through a workpiece, which comprises:
a) a bottom sawguide, said bottom sawguide having a front face and a second face, wherein said front face is enabled to contact and pre-strain a sawblade of a bandmill during a cut through a workpiece; and, b) a force sensor operatively coupled to said second face of said bottom sawguide, wherein said force sensor is enabled to sense a force associated with an incipient lateral deflection of a pre-stressed sawblade toward or away from said front face during a cut and to generate an electrical signal indicative of a magnitude and a direction in real time of said incipient lateral deflection from a true cut line.
