Abstract
Abstract A workpiece conveying apparatus for a working machine including provided with a slider rail arranged vertically on the body of the workpiece conveying apparatus, a drive source, a parallel link consisting of the slider link which is fitted crossing at right angles to and slidably in said slider rail, a slider arm, a lower slider link carrying a work holder and a sub arm and being connected rotatably with each other, a rocking lever being connected to the middle portion of the slider arm rotatably and rocked by a driving mechanism at a predetermined angle, whereby the work holder can convey a workpiece into or out of the specified position along with the intentional locus settled selectively so as to reduce the operating range, and keep a continuous working operation of the working machine, resulting in the durability of the working machine.
