The object of the present invention is to prevent the generation of abnormal operation or the delivering failure of a loader (5) like a gantry loader due to the displacement of the core of a chuck (2) when a work (W) is delivered to the chuck of an outer device, for example a NC lathe.
The present invention relates to a loader control device (20) for controlling the loader 5 which delivers the work (W) to the chuck (2) of the outer device (1). The work (W) is delivered by the loader chuck (14) placed at the work delivering position. The displacement of the center position of the loader chuck (14) and the center position of the outer device chuck (2) at the time being is detected by a displaced amount of detecting means 31 from the torque of the motors (11, 12) of the loader (5). An adjusting means (32) adjusts the work delivering position of the loader chuck (14) by the amount corresponding to the detected displaced amount, when delivering the next work (Fig. 1).
