Method and apparatus for carrying workpiece by continuous workpiece
carrying operation
摘要:
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.
