A mechanical loading device capable of generating a substantially rectilinear output motion for the purpose of transporting workpieces between work stations. The mechanical loading device is capable of producing the rectilinear output motion such that a workpiece is lifted, transferred horizontally, and then lowered into position with a significant degree of precision. The rectilinear output motion is generated primarily by a carrier on which a yoke is supported with an eccentric shaft extending from a driven member mounted to the carrier. The eccentric relationship between the driven member and the yoke, in conjunction with the controlled rotation of the carrier, generates the rectilinear output motion at an output member supported by the yoke. The mechanical loading device is structurally strong and compact, is constructed so as to be readily maintainable, and enables the efficient conversion of a rotational input motion to the desired rectilinear output motion. |
