CONTROL OF ROTATION REVERSAL IN AUTOMATIC OPERATION OF RECLAIMER

PURPOSE:To control the supply from a mountain of loaded material in a material yard at a predetermined amount by a reclaimer. CONSTITUTION:Angles of a range of a reclaimer in which rotation reversal is possible, are set for both sides as thetaLx+alphaLo to thetaLx-alphaLs, and thetaRx+alphaRo to the...

Zusammenfassung:	PURPOSE:To control the supply from a mountain of loaded material in a material yard at a predetermined amount by a reclaimer. CONSTITUTION:Angles of a range of a reclaimer in which rotation reversal is possible, are set for both sides as thetaLx+alphaLo to thetaLx-alphaLs, and thetaRx+alphaRo to thetaRx-alphaRs. Rotation reversal operation is carried out at a preliminarily set no-load current value of a hydraulic pump driving motor of a wheel hydraulic motor in the angle of the range in which reversal is possible. When an initial mountain after loading is supplied, at first, the supply for one rotation is carried out, and then the angles of rotation reversal operational position thetaLn, thetaRn are stored by the detection of no-load current value in the angle of the range in which rotation reversal is possible. From the next supply on, the values of rotational reference angles thetaLx, thetaRx are updated to the values thetaLn, thetaRn, each time the rotation is carried out.
