A workpiece magazine, for storing a relatively large number of workpieces before and after they are machined on an adjacent machine tool,has a vertically displaceable storage drum rotatable past a feeding arrangement for the machine tool. The workpieces are arranged in groups on intermediate floors in separate cassettes, one above the other, and the cassettes can be interchangeably suspended on the outer surface of the drum. The drum has two vertically spaced coaxial annular elements united by perpendicular struts, and the elements have holes spaced around their peripheries receiving pins on the ends of the cassettes. The upper element is constructed as an internal ring gear engageable with the pinion of a positioning motor, and the lower ring element forms a roller guide for an oil drip tray which is suspended non-rotatably therefrom. The cassettes are in the form of shaped angle sheet metal funnels or shells having apertures through which a workpiece injector may project into the cassette to eject a workpiece from a floor in the cassette. |
