A method and an apparatus for carrying a workpiece for improving efficiency in a workpiece carrying operation. In the apparatus, a moving member having a workpiece holding member is driven with a linear motion in a horizontal plane along a carrier passage, and the workpiece holding member is driven with a revolutional motion in a vertical plane around a revolution axis displaced from a center of the workpiece holding member, while the workpiece holding member maintains an orientation in which a holder holding the workpiece points downwards. The holder of the workplece holding member is controlled to sequentially carry out holding of the workpiece and releasing of the workpiece at lowest positions of the workpiece holding member in the revolutional motion, so as to realize a continuous workpiece carrying operation.

Method and apparatus for carrying workpiece by continuous workpiece

A method and an apparatus for workpiece installation capable of carrying out workpiece installation operation without a stopping of a rotational motion of a rotatable table member. In the apparatus, rotatable drum is continuously rotated while workpiece carrier member, provided along a circumference of the rotatable drum, for carrying a workpiece from a workpiece supply station to a workpiece installation station, which is capable of spinning on the circumference while carrying the workpiece, is controlled such that the workpiece carrier member spins while the rotatable drum rotates so as to move along a prescribed trajectory which is preferably a cycloidal or quasi-cycloidal trajectory, and that the workpiece is picked up by the workpiece carrier member at a prescribed pick-up position on the workpiece supply station and released at a prescribed installation position on the workpiece installation station.
