Handling machine with tilt and displacement sensors control
The granted patent US12071331B2 describes a handling machine featuring a main body and a telescopic handling arm that can rotate and extend. The machine is equipped with actuators for raising, lowering, deploying, and retracting the handling arm. A tilt detector generates signals related to the tilting moment on the main body, while displacement detectors monitor the movements or requests for movement of the handling arm. A control unit processes these signals to manage the handling arm's movement, specifically by slowing down, preventing, or stopping its motion if the tilting moment exceeds a predetermined threshold. The control unit can adjust the effective threshold based on whether the handling arm is being lowered or extended, with the lowering threshold set lower than the extension threshold.
Additionally, the patent outlines various configurations for the displacement detectors, including angle sensors that measure the tilt angle of the handling arm and length sensors that assess the arm's extension. The control unit can detect changes in these measurements to determine the appropriate movements of the handling arm. The handling arm can also be oriented about a transverse axis, and the tilt detector may include a strain gauge positioned on an axle to monitor deformation related to the tilting moment. The patent further details a method for controlling the handling machine, emphasizing the importance of monitoring tilting moments and movement requests to ensure safe and effective operation of the handling arm.
