PROBLEM TO BE SOLVED: To provide a drive command generation device of a work conveying device capable of avoiding interference with a die, and efficiently driving the work conveying device without degrading SPM (Stroke Per Minute).;SOLUTION: The drive command generation device 10 of the work conveying device comprises an operation panel 9 to input an interference area and a non-interference area of a slide, a rotary encoder 8 to detect the slide position, an area determination means 11 to determine in which area the slide is present based on the slide position, a lowest press selection means 12 to select a lowest press with the slide being lowest in the interference area, an interpolated value operation means 15 to operate the interpolated value in the non-interference area, and a command value generation means 16 which prepares an imaginary master slide motion following the slide motion of the lowest press in the interference area, interpolates the imaginary master slide motion with the interpolated value in the non-interference area, and generates the drive command of the work conveying device from the imaginary master slide motion.;COPYRIGHT: (C)2006,JPO&NCIPI
