PURPOSE:To properly control transfer operation to align the center of gravity of a coil with the center of a hook by computing the center of gravity position of a coil on the basis of coil load, and computing the running distance of a coil transfer loader on the basis of a computing result to control the coil transfer loader. CONSTITUTION:The position Lg of center of gravity of a coil in a coil transfer loader stand-by position is expressed by Lg=Gf.Lc/Gf+Gb-Lp wherein Gf is an output of a coil load detector 41 for a hook conveyer 1, Gb is an output of a coil load detector 42 for stand-by position, Lc is a distance between both detectors 41, 42, and Lp is a distance from the trailing end of a coil 2 located at a coil transfer loader stand-by position to the above detector 42. This is computed by an arithmetic unit 5 for computing the position of center of gravity of a coil. When the distance from the center of a hook 1 to the trailing end of the coil 2 located at the coil transfer loader stand-by position is Lo, the value of Lo-Lg is computed by an arithmetic unit 6 for running distance in order to align the center of gravity of the coil 2 with the center of the hook 1. The computing result is output to a coil transfer loader control unit not shown. |
