Clamp arm position sensing apparatus
First Claim
Patent Images
1. A clamp arm position detector for a clamp having a pivotal clams arm fixedly mounted on a rotatable shaft rotatable by an external power source between first and second end positions, the detector comprising:
- means, coupled to a rotatable shaft on which a clamp arm is mounted, for detecting the absolute position of the clamp arm at all positions of the clamp arm, the detecting means generating an output signal corresponding to the absolute position of the clamp arm;
means for establishing a set point corresponding to one angular Position of the clamp arm; and
comparator means, responsive to the output signal from the detecting means and the means for establishing the set point, for generating an output signal when the output signal from the detecting means corresponding to the absolute position of the clamp arm matches the set point.

Abstract
A sensor detects the absolute angular position of a rotatable clamp arm between full opened and full closed positions. The sensor is coupled to a clamp arm pivot shaft to provide output signals corresponding to the absolute position of the clamp arm. One or more programmable angular position set points are setable at angular positions in advance of the full open and full closed positions of the clamp arm. Outputs are generated when the clamp arm reaches and/or exceeds each set point.
