Abstract

A line of manufacturing units for carrying out a sequence of machining operations on a set of workpieces, which are fed in, in succession, at one loading end of the line and proceed along the line up to an unloading end of the line, comprises means for transfer of the workpieces along the line, the said means including a fixture made up of a plurality of horizontal supporting and guide beams, which are set in a superelevated position and which extend one on the prolongation of the other in the longitudinal direction of the line. Each superelevated beam carries a first mobile slide on top of it, upon which is in turn mounted a vertical upright (or a second mobile slide, which can move vertically), at the bottom end of which there is mounted a pick-up device, which can be oriented about a vertical axis. The movements of the various transfer devices are coordinated in such a way that, when one manufacturing unit terminates its cycle of operations on a piece, the transfer devices upstream and downstream of said unit are already close thereto for picking up the workpiece that has undergone machining and for loading a new workpiece.
