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.

Abstract: A device for loading and unloading a tool into/from the tool magazine of a machine-tool or the like comprises a door, which separates the area of the tool magazine from an external protected area, and a tool-bearing slide, which can be displaced between a backed-off position outside the door and an advanced position inside the door and close to the tool magazine. The slide is connected to the door by a mechanical transmission in such a way that a movement of advance of the slide causes a simultaneous movement of opening of the door, and a movement of backing off of the slide causes a simultaneous movement of closing of the door.

Abstract: Described herein is an oscillating-drawer device for loading and unloading tools into/from the tool magazine of a machine-tool.
